British rocker Matt Bellamy has vowed to "put a smile" on the faces of London fans when Muse perform in the U.K. capital this weekend (25-26May13) following the brutal killing of a soldier in the city on Wednesday (22May13).

Brits were stunned by the horrific death of 25-year-old Army Drummer Lee Rigby, who was hacked to death in Woolwich, south east London, and Bellamy hopes Muse's shows at the Emirates Stadium on Saturday (25May13) and Sunday (26May13) will give a boost to locals.

The band performed in New York on the same day as the Boston marathon bombings in Massachusetts last month (Apr13), and the singer wants to emulate the atmosphere of the Madison Square Garden concert.

He tells Britain's The Sun, "It was crazy in New York on the day of the Boston bombings. We were playing Madison Square Garden that night - and the atmosphere in the city was noticeably different from normal. It is difficult to choose the right words on stage on a day like that. You don't want to get into making a political speech, even though you feel strongly about what is happening.

"It's really sad but we have to find that element of balance because we are there to entertain and put a smile on our fans' faces. It brings back everything that happened in New York in 2001. It added a bit of a sombre tone to the gig but the spirit in the city shone through and everyone enjoyed the night in the end. We will do the same when we take to the stage this weekend."
