I had the chance to see INXS back in 1990 on the X tour, but alas, I didn't go. I was kind of broke at the time and I just didn't have the money. I do regret not going, but those are the breaks sometimes.
I guess if you wanna laugh, I'll name some of the concerts I had to turn down for various reasons:
U2- Joshua Tree tour(I was grounded)
Paul McCartney-1990 tour(broke)
INXS-X tour(broke)
The Cult- 1990 tour(broke)
U2--Outside Broadcast at Yankee Stadium(broke)
Well, most of the time, I just didn't have enough money to go these concerts. I was only 18 or 19 years old at the time and not making much money yet. But, I did actually wind up buying Live Baby Live by INXS to make up for missing them.
