I won't argue with someone who was at the 801 Live show!
Anyway, I was told the 1974 tour with Yes, Peter Frampton, and Gary Wright was just incredible.
I saw Yes two years back at an ampitheatre (played Ritual, Gates!). Saw them several years prior, with the orchestra. The Union tour was sweet, also. Awaken (or shoud I say Awakeman) was the highlight. Also been to a couple Rabin-era Yes shows. A bit more arena-style and bombastic.

I was happy to see Yes in their current form - the past three or four tours have had the best line-up and song selection since the 70's. I don't think I'd shell out big $ again (even Rush shows are enough at these prices). I've seen them and the smaller shows have been kind to me.
If you've never seen Yes, do it.
