Any of you in the know on this one?

I recently read that Sir Paul McCartney's kid brother Mike has a completely different personality from Paul. In what ways do they mean? The passage didn't go on further to elaborate.

I know from photos I've seen of him he doesn't bear much family resemblence to Sir Paul. First off, he's a redhead who looks more like the Irish-American comedian Denis Leary than he does Paul McCartney. I think he looks more like Sir Paul's mother's side of the family, the Monin's.



Any insights into Mike's personality?
