That first Def Leppard concert would've been amazing. God I wish SB older bro had given 5 year-old SB that Hysteria tape sooner. Still, the Adrenalize concert was a pretty great way to lose my concert virginity too, even if the arena really was only half full.
And mocat, Soul Asylum and Ben Folds both lost tons of money. UPC brought in rock concerts a fair amount and tried with Soul Asylum but only like 1,500 people showed up (including SB). So they swore it off for a long time and broke their own rules for Folds years and years later and I think they prolly regretted it.
