I heard my Dad's LP, 9012Live: The Solos. It was the first LP I ever played. The solos were really good. This LP is the only official release where people can hear "Si". "Solly's Beard" was really good and "Amazing Grace" was better than the bonus track on GOING FOR THE ONE. "Soon" sounded very different in the era of this tour. "Whitefish" is different from later versions because the "Sound Chaser" part is recognizable and you can hear Jon saying "Yes, Yes" on the "Tempus Fugit" part.
What bugs me is that the album is only 34 minutes long. There could have been enough room for "I'm Down" or a classic Yes song like "And You And I" or "Yours Is No Disgrace".
