Your First Concert was.....

11/17/73 - Focus, with the Spencer Davis Group (no Steve Winwood) opening, at the Felt Forum (now known as The Theatre at Madison Square Garden).

My friend and I bought tickets just a few days before the show and ended up in a row of folding chairs set up in front of the regular seats. Man, it was loud.

Next up would be Yes at MSG on the 'Tales From Topographic Oceans' tour.

Allman Brothers either at the Georgia Tech Collesium or the Atlanta Civic Center 1970. I saw them at both that year.
They were always playing in Piedmont Park, which is where I first saw them, but I am not sure that qualifies as a concert or just a gathering of Hippies :-)

I saw Focus as well. They played Hocus Pocus and variations of it the whole show. It was still fun. I saw the Allman Bros just when Duane died but Berry was still alive. They did not cancel the tour.

Joe Walsh and James Gang for openers, followed by REO Speedwagon.

Jackson Browne on his "Running on Empty" tour at the great outdoor Blossom Music Center in Ohio. I played that album hundreds of times before I went and I'll never forget the sound of the first note of that live music, magical. Thanks for taking me back. I still have the LP.
