Brian Austin Green went to the Hamilton High School Academy of Music.
Harold Perrineaux has his own band and is recording.
Not sure about the other two, but they look like they're workin' it.
Funniest line was the last one in the episode with Megan Fox in it. The band's watching the finale of the TV series her character's in, and Harold's character says something like "that's the second worst ending to a TV series I've ever seen!"
