London's Billy Elliot has been busier than usual recently, as the cast and creative team get ready to blow out the candles on the show's upcoming fifth birthday. On March 8, the production's four current title stars got a break from rehearsals and performances with a trip to Downing Street to meet Prime Minister Gordon Brown. Stars Dean-Charles Chapman, Tom Holland, Ollie Gardner and Fox Jackson-Keen were personally invited by Brown, who treated the quartet to a tour of historic Downing Street before taking a private meeting with his guests. Afterward, the boys also met with Chancellor Alistair Darling, Minister for Culture and Tourism Margaret Hodge and Peter Mandelson. The ballet girls will be so impressed!
