Sir Paul McCartney has revealed the biggest rivalry in The Beatles was between John Lennon and George Harrison - over whose guitar was loudest.
Macca claimed the late stars would sneakily tweak each other’s amps to pump up the volume.
He said: "There is going to be the odd argument – and there were.
"George and John were very cute because they both had their amps side by side and you’d see one of them just sort of sneak over to the amplifiers, just add one degree and then you’d see him walk back like nothing had happened.
"And then you’d see John had noticed and John would casually walk over and put his up two degrees. ‘You’ve f***ing turned up man!’ ‘What? I never did!’ ‘Yeah you f***ing did!’"
Sir Paul, 79, compared bust-ups between the Fab Four to rows between relatives.
He said: “You know I remember having an argument with a member of my family, one of my kids once, in front of someone.
