Hi Faith ! Yes, I have a few regrets too. Had a chance to see Pink Floyd in 1994 and passed it up. ( Ugh!!) Guess I can always see their tribute band ( Brit Floyd). Had tickets to see Led Zepplin in 1980 but John Bonham died and the tour was called off. Have seen Billy Joel 3 times; always a top notch show. BJ played at my college the year before I started there; would`ve loved to see that !
