What can you say?  Despite poor quality, it's a classic.  Not something I'll view very often, but certainly something I love having in my collection and will play once in a while.  These were great days, indeed, for music, bands and the industry in general.  And Yes will always be among the best bands of all time.  Period.  They were THAT talented, all the way around.  Original, creative and powerful, yet did some of the most beautiful music ever done by a 'prog' band.  They had it all.
