Live in Concert is the second live music video title by singer and actress Cher. Released by HBO in 1999, it contained footage from Cher's Do You Believe? Tour specials filmed at the MGM Grand Garden Arena in Paradise, Nevada in 1999. It featured tracks from the Gypsys, Tramps & Thieves album to the Believe album, alongside various covers. She has 7 costume changes by stylist Bob Mackie.
Cher changes costume more than 7 times in her Live in Concert music video.
Technically she only changes 7 times, so the paragraph says, however, if you want to count the clothes she came in for the day, it would be more than 7.
