I was lucky enough to see this lineup on the London date. It's a pity it wasn't sustainable but the DVD is a wonderful recording, apart from the bewildering level of fake crowd noise plastered randomly over the top.
Lee Pomeroy - wonderful. I've never seen a bass player project so much joy when playing.
As for the current 'official' Yes, well... a quick look at Geoff Downes attempting to play Wakeman and Moraz's parts tells you everything.
