I’ve not heard this stuff at this sound quality level. Fun. Best was an amateur, hobby drummer. In those days, if you had a set of drums (very expensive!), you were begged to play with some very good musicians. These Decca recordings illustrate how important Ritchie was to the Beatles sound. No wonder they didn’t get signed at this point. ( plus, they were essentially a cover band at this point) Having said that, if the Beatles had a seasoned pro drummer other than Ritchie they would have been fine. As someone else said, it’s always been about the songs they wrote and sang.
