George and John were very cute because they both had their amps side by side and you’d see George 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. [laughs] ‘You’ve fucking turned up man!’ ‘Wot, I never did!’ ‘Yeah you fucking did!’ - Paul McCartney
