A friend of mine's dad used to tell a great story about how he was hiking in the Lake District once, and he went into a pub for lunch, where Engelbert Humperdinck and Tom Jones were getting p*ssed. (This isn't a joke- as far as I know, it was real- they were mates, after all). It's kind of a long story, but essentially Tom Jones was being an absolute d1ck, and trying to get him kicked out (he was the only other person there) because it was their pub, and he wasn't signing autographs. My mate's dad kept saying he didn't WANT TJ's autograph, which just made TJ angrier... eventually EH came over, apologised for Tom's drunken behaviour, and bought him a pint.
I really HOPE that's true, because it's the most awesome anecdote I've ever heard.
