HAYWARD -- A woman was arrested Saturday after allegedly jumping on stage at a music festival and attacking a legendary musician after he dedicated a song to Trayvon Martin, according to police and eyewitnesses. 
 
 The woman, who police identified as 43-year-old Dinalynn Andrews Potter of Barstow, apparently yelled, "it's all your fault" before shoving 73-year-old Lester Chambers, his family said Sunday. 
 
 "She had a crazed look in her eye," said Kurt Kangas, a friend of Chambers who ran to his aid. "I saw the devil there." 
 
 Chambers was performing at the Hayward Russell City Blues Festival downtown when around 5:15 p.m. he dedicated Curtis Mayfield's hit "People Get Ready" to Martin, the 17-year-old shot and killed by George Zimmerman. 
 
 A Florida jury acquitted Zimmerman on all charges Saturday. 
 
 Chambers told the audience if Mayfield were around today, he'd change the lyrics "there's a train a comin'" to "there's a change a comin,'" his wife Lola Chambers told this newspaper Sunday. 
 
 "She must have been an acrobat. She did it in one leap. He didn't see her coming," Lola Chambers said. 
 
 Eyewitnesses and Hayward police said people on stage subdued Andrews Potter after she allegedly shoved Chambers. Though the police investigation into a motive continues, family members believe the attack was racially motivated and was a result of Chambers' mention of Martin. The family is pressing police to file hate crime charges. Andrews Potter is white, they said. Chambers is black.

 Hayward police took Andrews Potter to the police station, where she was arrested on suspicion of battery. She was cited and released, and could face additional charges in the coming days, according to Hayward police Lt. Ruben Pola. 
 
 Chambers, a Petaluma resident, was taken to the hospital but has since been released, and is using a cane to walk. A photo his son posted on Facebook shows a large welt on his backside. His son said Chambers had a "bruised rib muscle and nerve damage and he is sore all over." 
 
 Chambers was a member of the 1960s soul group Chambers Brothers and has had a well-publicized fight with record executives over decades of royalty payments he said he has never received. 
 
 The Chambers Brothers will be part of the inaugural class inducted into the R&B Hall of Fame later this year, Lola Chambers said.

Follow him at Twitter.com/daviddebolt. ||||| Lester Chambers, a seventy-three year-old musician known for his work as a member of The Chambers Brothers, was assaulted on stage at a blues festival last night after he dedicated a song to Trayvon Martin. 
 
 Chambers’ son, Dylan, posted the following on Facebook last night: “Lester was just assaulted on stage at The Russell City Hayward Blues Festival by a crazed woman after dad dedicated People Get Ready to Trayvon Martin. He is on the way to the hospital now.” 
 
 Kurt Crowbar Kangas, a musician and friend of Lester’s, later posted in the comments thread: 
 
 Lester is fine, just a bit sore and he will feel it tomorrow, the woman who attacked him was white and yelled something like “it’s all your fault” before she hit him, he went down hard but was halfway caught by Barren, thank God, she was subdued by Police and taken away while the para-medics came and took him to a local Hospital where he went thru a series of cat scans, no broken bones, the only injury for now is a 8″ scratch in the kidney area of his back and it’s starting to swell. Thank you for all your well wishes, he will be up and running soon. 
 
 Lester apparently dedicated the classic song, “People Get Ready,” by The Impressions to Martin. The woman heard the dedication and attacked him. 
 
 His son posted a photo of Lester’s injury to Facebook. He said he had a “bruised rib and nerve damage” and was “sore all over.” 
 
 There was a lot of talk, particularly by Zimmerman supporters, about how there would be riots if Zimmerman was acquitted. So far, all that we know happened that was violent was this attack and an attack on peaceful protesters by the Los Angeles police, who fired rubber bullets at them. 
 
 Over fourteen months ago, Lester posted an “I Am the 99%” photo. The Occupy movement was still making headlines and a sign he held up read: 
 
 I am the former lead singer of a 60′s band. I performed before thousands at Atlanta Pop 2, Miami Pop, Newport Pop, Atlantic Pop. I did not squander my money on drugs or a fancy home. I went from 1967-1994 before I saw my first royalty check. The music giants I recorded with only paid me for 7 of my albums. I have never seen a penny in royalties from my other 10 albums I recorded. Our hit song was licensed to over 100 films, TV and commercials without our permission. One major TV network used our song for a national commercial and my payment was $625 dollars. I am now 72, trying to live on $1200 a month. Sweet Relief, a music charity is taking donations for me. Only the 1% of Artist can afford to sue. I am the 99%. 
 
 He told VICE in an interview in May 2012 other musicians were in “the same boat” as him. 
 
 “There are so many. And so many different members of different bands. There are a lot of cases where two or three members did well and two or three didn’t. So many, I can’t begin to give you names,” Lester said. 
 
 The good news is that Lester has recorded a new album after raising over $69,000 with a Kickstarter project. It is an opportunity for the “internet public” to right a wrong committed by the music industry. 
 
 “People Get Ready” is a song that The Chambers Brothers recorded for their album “The Time Has Come” in 1967 (which included a version of the group’s most well-known song, “Time Has Come Today”). 
 
 The song reflected the times. Written by the late great musician Curtis Mayfield, “People Get Ready” was written after Martin Luther King Jr. led the March on Washington, and it resonated with those fighting racial injustice and oppression because of the universal gospel message that, if people continued to persist in their struggle, they could prevail. 
 
 As the song goes: 
 
 People get ready, there’s a train a-comin’ You don’t need no baggage, you just get on board All you need is faith to hear the diesels hummin’ Don’t need no ticket, you just thank the Lord 
 
 It is an incredibly appropriate song to dedicate to Trayvon. There may be no punishment for what George Zimmerman did when he killed Trayvon, but don’t let this be demoralizing. Keep on fighting. Challenge the law that gives self-appointed vigilante neighborhood watchmen the cover to claim self-defense after profiling a young black teenager and escape having to serve serious time in jail. 
 
 Here’s Lester Chambers performing “People Get Ready” earlier this year:
– A 73-year-old black soul singer in California got roughed up Saturday by a woman in the audience who rushed the stage after he dedicated a song to Trayvon Martin, say police. Lester Chambers was talking about the George Zimmerman trial and about to play "People Get Ready" when a white woman leaped at him, shouting, "It's your fault," witnesses tell the San Jose Mercury News. Dinalynn Andrews Potter, 43, was arrested on suspicion of battery, and the Chambers family is pushing police to file hate-crime charges, too. "She had a crazed look in her eye," says one of the musician's friends who rushed to help him. Chambers suffered a bruised rib and nerve damage and is "sore all over," according to a Facebook post by his son. "People Get Ready" is a Curtis Mayfield song written after MLK's march on Washington, and Chambers' old group, the Chambers Brothers, recorded a version in 1967, notes Firedog Lake. In his dedication to Trayvon, Chambers had said Mayfield would have written the line "there's a train comin'" as "there's a change comin'" had he penned it today.
