Maybe he's like the incredible hulk and grows when he sticks a setlist to his head (what other reason is there for sticking a set list to your head?)
Check out how huge he is compared to the people peering over his shoulder. I think they just climbed up his back, maybe to try and remove the setlist before he demolished the venue. Or maybe he's a gentle giant but they were worried about fitting him in the back of the Mini for the drive home. Don't you hate it when you're driving and you have a pair of knees digging in your seat?
