Hollywood funnyman Jack Black thrilled clubbers in London on Saturday (15Aug09) by taking the stage at a karaoke night and belting out his favourite tunes.
The King Kong star - who also fronts rock band Tenacious D - made an appearance at hip venue Jalouse in the British capital with his castmates and crew from upcoming movie Gulliver's Travels as they celebrated the end of production.
Black was quick to hijack the club's karaoke machine, taking the stage with a rendition of War Pigs by Black Sabbath.
He then pulled his wife, Tanya Haden, up to sing Michael Jackson's Beat It.
A source tells British newspaper the Evening Standard, "The crowd loved it - they went absolutely crazy and he put on a real show, as you'd expect from Jack. Most people could have watched him all night, but he didn't hog the mic and graciously stepped aside for everyone else to have a go."
