Ringo Starr has said that The Beatles' musical ability wasn't helped by screaming fans during their mid-sixties heyday. He says: "By 1965 we were turning into really bad musicians because we literally couldn't hear ourselves over the screaming from the audience. I was going downhill as a musician, and so was everyone else in the band".
He adds: "Then, we only did 25 minutes on stage. Now thanks to Led Zeppelin and The Who, everybody has to do two hours".
Well, I should think so too. Actually, I might retract that. Even my favourite bands get trying after an hour.
