Sir Paul McCartney has played his first U.K. gig since his divorce battle with estranged wife Heather Mills went to court. The former Beatle rocked the BBC Electric Proms on Thursday (25Oct07) when he took to the stage for a one-off London show at The Roundhouse in Camden. More than 80 acts are taking part in the five-day event, including The Kaiser Chiefs, Jamie Cullum and Edwyn Collyns.
