When Homer is secretly videotaped complaining about his family during an episode of 'Taxicab Conversations,' they send him off to a rock and roll fantasy camp so that he can regroup and try to live his dream.
Once there, he lives the life of a rock star, as taught to him by the likes of Mick Jagger, Elvis Costello, Keith Richards, Brian Setzer, Tom Petty and Lenny Kravitz. When the camp ends after a week, Homer doesn't want to leave. He just wants to rock.
Mick Jagger then invites Homer to come on stage for a benefit concert they're giving. Once on stage, Homer realizes that he's not a star, but just the groups Roadie. Homer decides to then wail on a guitar and introduce the band with a musical number of his own. Mick, Elvis, Keith, Tom, Lenny and Brian try to run Homer off stage and a riot breaks out at the venue.
In the end, the rockers apologize to Homer for their behavior and ask him to come on stage for another benefit concert. Homer declines however, saying that he's already the rock star of the Simpson family, so there's no need to go on stage any longer.
