I have seen Yes many times ( 3 or 4 in the 70s and a couple of times in 2000
Back in the 70s I had the chance to meet Jon Anderson (vocalist t that time) as was supposed to meet Christopher Squire that same time. He was giving an interview with Rolling Stone (I guess they were a bit more important than me...) so I did not get the meet.
Like those posing here, I have been a big Yes Fan, and Richard Wakeman Fan and Steve Howe too.
When I think of Yes, I think a tour they did called "In the round" with a circular stage that rotated clockwise, whilst Wakeman was in the center covered in keyboard turning counter clockwise. Anderson on one 'corner, Squire opposite him and Steve Howe in another and Alan white on percussion in the other. One of the best, most clear sounding concerts I ever saw. So close to studio sound it was almost like wearing headphones....
