I'm partial to DSOTM.
Always was more of an ELP fan, though. Have seen PF, Yes, and everyone else in Buffalo, but ELP always put on a good show there. Had some friends that were (long story) hooked up with Moog industries. Got to go to the Ralph for soundchecks, meet the band, etc when they played the concert with Lynard Skynard and James Gang.
Man, I might be showing my age, but these kids don't know how to party. Good time was Summer Jam at Watkins Glenn. I could go on for hours if I could remember it. The walk up the mountain was worth the price of the trip.
