|Rock legend SIR PAUL McCARTNEY busked in disguise in London for a new film.|
The former BEATLE blended in anonymously on the British capital's underground railway system - and only aroused the suspicion of a handful of passersby.
He says, "It was for a film, so I scruffed myself up a bit, put on a false beard and shades, and went down to Leicester Square tube station. A couple of people came up and said, 'Is it you?'
"But I just said, 'Oh no!'"
