The TOYPAJ tour was my first concert too. It was originally scheduled for September 14, but it got postponed a week because of 9/11, and I almost didn't get to go. Midtown and New Found Glory opened (Sum 41 was supposed to play instead of Midtown, but they didn't do our show, probably because of the postponement).
But yeah, it was a lot of fun. I definitely remember the giant, flaming "FUCK" behind them
