Tiger, at the risk of sounding nasty, that's absurd.
Paul was in TOTAL control of Wings. They were, for all intents and purposes, his sidemen. Do you REALLY think Denny Laine got final say on ANYTHING in that band, never mind Denny Seiwell, Henry McCullogh, or Jimmy McCulloch?
The Beatles were a democratic group. Right down to financial shares. Ringo had as much say, from what I've read (and I've read plenty), as John or George or Paul on MOST things. He just didn't happen to write songs or sing many. George was frustrated, sure, but he sure as hell had his say and his influence (India, Indian music, etc.). Can you imagine Joe English saying one day, "let's all go to Norway and study their fishing techniques!" and Paul dropping everything in, calling a press conference, and telling the world that, yes, he and the rest of Wings will be traveling to Norway, based on Joe English's words of wisdom, to search for "the way!"
Ringo and George both LEFT the band at various points, and were welcomed back with open arms and flower arrangements.
When Denny Seiwell and Henry decided not to go to Africa to record BOTR, that was the end of those two.
Hell, it's taken years for Paul to even acknowledge Denny Laine over who knows what slight that occurred over 30 years ago. Do you think that would have happened with any of the other Beatles?
Please. Let's not compare apples and oranges.
in years to come/they may discover/what the air we breathe and the life we lead are all about/but it won't be soon enough for me
