If you watch the scene when the Jackson 5 are performing "Twist and Shout" at the Apollo, you won't be able to miss this one. After the camera cuts to the individual brothers singing "AHHH" in the middle of the song, Michael runs to stage left in front of Jermaine and continues to sing ("shake it shake it shake it baby"). Watch Jermaine - his bass guitar slips out of his hands and picks it back up, all the while singing and smiling. OOPS!
