paul mccartney was known really as the lead beatle. though to common misconception, the best beatles songs were actually written by george harrison, not mccartney or lennon. paul also was known to pass on good ideas. I.E "while my guitar gently weeps". mccartney said it would never make the record and that it would be a mistake to record it. Harrison prevailed and got eric clapton (see god for more on eric) to play on the track. While my guitar gently weeps is known to lots of beatles fans as the best beatles song ever written.
