My Guitar Wants to Kill Your Mama

"My Guitar Wants to Kill Your Mama" is a song written by Frank Zappa and originally recorded by The Mothers of Invention in February 1969 at Criteria Studios (Miami), with overdubs recorded sometime between March and May 1969 at TTG Studios (Los Angeles) and Whitney Studios (Glendale, California). This version was included on their 1970 album "Weasels Ripped My Flesh," an LP that included various recordings by the band from 1967 to 1969. A second version was released as a single on the Bizarre and Reprise labels as "My Guitar." Despite the more conventional naming, "My Guitar" did not chart.
The single version of the song, recorded in June 1969 at A & R Recording Studios in New York City, differs from the album version, includes a longer break before the second verse is reprised, and is roughly half a minute longer. A shorter edit of the single version has been released on "You Can't Do That on Stage Anymore, Vol. 5".
His son Dweezil Zappa's 1988 solo album is named after the song and contains a cover of it, both as a tribute to his father. An a cappella version of the song is included on The Persuasions' 2000 Frank Zappa tribute album, "Frankly A Capella: The Persuasions Sing Zappa." The song was also covered by Joe Satriani, Steve Vai, and Eric Johnson on the 1996 G3 tour.
The song was used in the show "Daria", on the season two episode "That Was Then, This Is Dumb."
