It’s interesting that The Beatles have always been considered a true band, with every member as theoretically important as the others. This despite the fact that John and Paul wrote and performed 90% of their songs. Contrast them to The Rolling Stones, where Mick Jagger and Keith Richards share the spotlight and most people probably couldn’t name all the other members of the band. But everybody knows John, Paul, George and Ringo.
Ringo is certainly the main beneficiary of this. He wrote only a couple of the band’s songs and, while he’s certainly a fine and under-appreciated drummer, he’s not really the architect of The Beatles’ sound in any real way. His main contribution was his personality and considering the importance of the band’s image and performance outside the studio, that was no small matter.
