In the middle of the movie, go to the part just after the touring montage, just before the musicians are singing "Dance With Me Tonight". A reporter is interviewing The Wonders in front of a big TV camera.

When he first starts talking to them our view is off to the side. Lenny is standing to the left of everybody and the reporter is standing in the middle of the group.

While the reporter is talking our view moves behind the TV camera and we are looking at the picture on the TV camera's viewscreen. Lenny has somehow "jumped" from the very left of everybody to now be stand right next to the reporter.
