Sir Paul McCartney spotted tipping London busker Charlotte Campbell at Charing Cross Station

A busker was left “absolutely speechless” after a man who dropped money in her guitar case outside a busy London station turned out to be Sir Paul McCartney.

Charlotte Campbell was singing outside Charing Cross station when a passer-by stopped to listen to her singing one of her own songs.

It was only when 77-year-old Sir Paul dropped some coins into her case that she looked up and realised the Beatles legend was standing in front of her.

The full-time musician, 30, was “absolutely speechless” at first but managed to utter “thanks Paul” as he turned away.
