In 8 years they put together a song catalog that the Rolling Stones could not do in 40 years. Like them or not they are the most successful and influential band in history and its not close.
Led Zeppelin, Metallica, AC/DC, Rush, and Aerosmith vehemently disagrees with you.
Clearly the most influential band in history, and on my daily playlist.
As for who was the best drummer among the Beatles? Lennon could have been joking, but it may have been Paul McCartney, who came up with the drumming pattern on Ticket to Ride, where the drum lags behind the beat on the first half of the song. (McCartney also played lead guitar on Ticket to Ride.)
McCartney played the drums on some of the White Album (Back in the USSR; Ballad of John and Yoko; Dear Prudence; Honey Pie; Why Don't We Do It In the Road).
Yesterday was the 50th Anniversary of the theatre release of Hard Day's Night - on the eve of Ringo's 24th Birthday.
