Okay, I forgot about Union. But that wasn't the point of my post, even though now, re-reading it, I can see how it came across that way.
I guess I skipped a step. My point was that three former members of Yes who all chose to leave the band at least once, some multiple times, are now calling themselves "Yes featuring Blah Blah Blah", while the actual band Yes is still active and still touring. I skipped to the part where people argue about who has the most "legitimate" claim to the band name due to having the most original members and/or having played on more Yes albums. And because I was in a hurry, I didn't structure any of the argument that well.
So forget original members and number of albums. Three guys who all quit Yes voluntarily are now specifically promoting themselves as Yes. They are "the voice of Yes", "the guy who saved Yes from obscurity in the 80's", and "the guy who thinks he's the one everyone thinks of as the keyboard player when they think of Yes".
Caveats:
-- I know, the name of their new band isn't "Yes", it's "Yes featuring...", but come on. "Asia featuring John Payne" anyone?
-- The "voluntarily" part is also debatable, depending on who you believe, and we as the general public will never know all the facts. But there are a lot of facts out there, or at least a lot of views from those involved, and when everybody except one person says it went down a certain way, you tend to believe everyone else and not the one guy, especially when it's the one who seems the most wronged in their version of the story.
