November of 73, senior year of high school. Focus, riding high on "Hocus Pocus" all over the radio, at the Felt Forum, now called The Theater at Madison Square Garden. Bought tickets very close to date of show, and ended up in the second of two rows of metal folding chairs at the front of the room, apparently hastily added after the regular sears sold out. It was wonderful and VERY LOUD. Next stop, MSG's arena for Yes on the Topographic Oceans tour in February of '74.
