I've never been a huge concert guy. My dad was, and said he's a top 5er. Saw him for the last time (he thought) at the Palace about a decade ago and said he still had it.
A cook I worked with at a summer job said he worked a Tom Petty concert once, doing the food prep for the suites. He said they got a special order to deliver back stage after the concert was over just for huge trays of crackers, cheese and cold cuts. Went and delivered it back stage, and it was Tom's room. Opened the door, and he said the second hand high he got was strong. Just dropped off the trays and turned around, one of Petty's crew handed each of them two $100 bills on their way back out.
