Jer, that was A-W-E-S-O-M-E !!! South Side of the Sky is a Yes fav of mine and they were in top form during this performance which I have never seen. The vid looks and sounds great too. Howe is one of my all time favorite guitar players so watching him on his Gibson ES-175 duel with Wakeman on the Moog Synth was very cool.
The other guys were OK too I suppose

Thanks for sharing
