Once set up, you should get the Anderson, Bruford, Wakeman and Howe DVD. It is by far my favorite. I have Songs of Tsongas and the Blu Ray of Montreau, but they don't quite measure up to the first. Yes, you might miss Chris Squire, but Jeff Berlin does a great job of standing in (for Tony Levin). Plus, Yes has slowed down quite a bit in tempo in their more recent stuff. Don't get me wrong, I still like it.
On ABWH, they are quite younger, and smoke!!!!!!! It is to bad the video and sound quality sucks on Yessongs.
