[a fool in paradise]

Even the rich a famous can get tired of living a Bubble Boy type of existence.

It's made Ringo bitter (being a Beatle Bubble Boy). When people ask him "What's it like being a Beatle, he says "what's it like NOT being one?"

[Hugin]

That doesn’t sound bitter to me. It sounds like a wry observation on relative perspective. He’s never known anything other than being a Beatle, at least as an adult.

[HerrBlucher]

He should ask Pete Best.
