IamA guy who worked for Katy Perry's Superbowl halftime show AMA!
I helped push stage lighting on and back off of the field for halftime. There wasn't much to it really, but I learned and saw a lot. It was certainly an experience!
(I don't know if that's enough proof, but I can find more if needed)
Edit: Time lapse of the stage construction My cart is a black lighting cart near the bottom left side at around the 15-20 yard line.
MOST IMPORTANT EDIT Turns out you might be able to get a shark suit soon.
