Eddie is very cool. I don't think he gets enough credit. My first exposure to him was U.K., wherein he played keyboards and electric violin, and man, he rips on that violin! ♫♫ He's also great on keyboards. For whatever reason, he's not very well known, and hasn't done a whole lot, considering how long he's been around. But I've always liked whatever he contributes to the bands in which he's played.
And yeah, I was going to mention him in the Yes Discography thread. He's barely more than a footnote, but as he was an official member of the band, I'll have to work him in somehow. Probably just say pretty much what I said above about him.
