in an interview with I think Rolling Stone magazine, Lennon was really nasty to Macca, accusing him of ruining his songs by recording them with a boring and unimaginative bass parts, while his songs were adorned with beautiful lines crafted for them. I for one cannot understand what he is talking about! Macca laid some lovely lines for Lennon including Mr Kite and most of the white album especailly the slow version of Revolution! Lennon played bass on Long & Winding Road and made a right hash of it! At least Macca never left any blemish on a released recording!
