Just another thought on why Paul gets criticized and Prince doesn't... Perhaps its because Prince never had a songwriting partner like Lennon. Even though I believe Paul is a greater lyricist, it is pretty hard to live up to the mythology of Lennon. Sure Prince has collaborated but never with anyone the size or stature of Lennon. Just another thought on this question.
MHNSO- I think the only connection being made was in their prolificness (if thats a word). And no kidding about his guitar playing, very few guitarist have ever made my draw job while I watched them play, but he sure did.
