wonder which one i have
 

in college, my friends used to have a lot of bootlegs running around. I never got into that, but I sill have on dusty cassettes a Rush from 1977, a 1978 Genesis, an Zep, and a Floyd. I think it's the King Buscuit (sp?) Flower Hour - got fat Old Sun, One of These Days, and Echoes.

I think it's quite good up until about the 17minute mark. There's a logical stopping place, but then they go into this avant-garde weird keyboard thing with bits of the earlier section in the background. They should've lopped it off there and had another 4 minute song to fill that side, IMO.
