An avid autograph hunter picked an unusual time to ask for Sir Paul McCartney's signature - in the middle of a live performance being broadcast by the BBC.
The fan was in the audience of only around 200 people, made up of listeners and guests, who were watching the intimate show at the Maida Vale studios in west London.
Sir Paul seemed bemused by the request as he played a handful of new and old songs during a session for BBC Radio 6 Music, at the studios he last visited in the 1960s with The Beatles.
"What? Now?" he asked the cheeky fan. "I love it - there's one in every crowd. As if I don't have enough to do to remember the songs and the chords."
