Palmer is playing in a club here at the end of the month and I'm still undecided as to whether or not I should go. The show will probably be good of it's own right, but it wouldn't be the same as seeing the three of them together. I've only ever seen the three of them together. Yeah, Palmer is a great drummer to watch, but it's not the same. I have the same feeling about Bill Bruford - even though he's spent more time with others, to me he's the original drummer for Yes.
From what I read about their breakup in 1997, it semeed to be Greg Lake vs Emerson/Palmer, and it was very acrimonious. While I'd love to see them get back together one last time, I doubt it will happen.
