Rocker Duff Mckagan showed his support for Britain's armed forces by performing for five soldiers in London on Monday (29Oct12).

The Guns N' Roses bassist staged the one-off special gig in aid of Help For Heroes, a non-profit foundation benefiting wounded servicemen and women.

MCKagan admits he was nervous about playing to just five fans, despite performing for a crowd of thousands at Wembley Arena in the U.K. capital on Sunday (28Oct12).

He says, "These guys are incredible. I'm scared performing for such a small crowd. I played Wembley last night but this is much scarier!"
