Following her triumphant performance at the O2 last week, Lady Gaga will return to the capital later in the summer. She of the rapidly oxidising underwear has added several new European dates to her Monster Ball Tour between May 7 and June 4, including another show at the O2 on May 30. Tickets go on sale on March 12. At the more venerable end of the pop pantheon, Sir Paul McCartney is gearing up for a series of UK gigs this summer, including a concert in Hyde Park on June 27. Macca will also play the Isle of Wight Festival, Hampden Park Glasgow and (one night before Hyde Park - where does he get the energy?) the Millennium Stadium in Cardiff. Tickets for the London gig go on sale March 5.
