THE Beatles drummer Ringo Starr was disgusted with the band's musical prowess in the mid 1960s - because their screaming fans turned them into "bad musicians". The Fab Four star is convinced they became victims of their own phenomenal success, as the deafening roar of the crowds during their gigs drowned out the sound of their instruments - so they couldn't hear what they were playing. 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. Then, we only did 25 minutes on stage. Now thanks to Led Zeppelin and The Who, everybody has to do two hours."
