dang hard to remember, I'd guess the first was in '72 or so in Spfd. MO, the Guess Who (no don't guess, that was their damned name) they had a hit Magic Bus IIRC
but made up for my slow start, have seen a bunch of good ones particularly when I worked for WEA (Warner, Electra, Atlantic) and lived in Chicago
here goes, not in order just as I recall
Frampton,
Black Oak Arkansas
Molly Hatchet,
Zeppelin, twice
Pink Floyd, at Soldier Field
Ted Nugent at the Amphitheater
Tom Waits
Genesis, when they had Peter Gabriel and Phil Collins
Roxy Music
Cheap Trick
oh god this is too hard, there's more, but yeah I got to go to some good gigs.
even setup rooms for some of the bands, in fact someone mentioned Elvin Bishop and those guys were outa control with their demands, wanted girls and uncut cocaine, told em if I knew how to score those anytime i wanted i sure wouldn't be babysittin rock stars
oh chit almost forgot Lou Reed, but Ian Drury and the Blockheads opened for ole Lou and stole the freaking show, they were incredible
oh the Tubes
f this, too long ago and too many of them
