I remember someone telling me that Ringo once said he was the best drummer in the world... and Paul or John responded to him... rubbish, your not even the best drummer in the Beatles.. dont know if that really was said... but hey, it's pretty funny...
Here is Paul on drums in 1974 w. Lennon, Stevie Wonder, and friends during the Toot and Snore recording session... these were recently unearthed and worth a listen... (for curiosity's sake only)...
