Pink Floyd, didn't have a ticket, went to Rupp Arena, I think it was in '87. Got 3rd row for $20. Was amazing.
Tom Petty and The Heartbreakers at Louisville Gardens, it was his opening show for that tour.
Saw John Fogerty at Louisville Palace, he played for a about 3 hours straight and at one point brought out his amp and said, "I know this amp looks old, but I'm kind of partial to it. I had it with me at Woodstock."
