It's a long time since Moulin Rouge, but Ewan McGregor is flexing his vocal cords again.

The actor stars in the new video for Radio 1 favourites Catfish and the Bottleman - after the band staged a somewhat creepy campaign to get his attention.

Singer Van McCann stitched together a three-minute montage of McGregor's smiling face to soundtrack the song Kathleen ; while drummer Bob Hall played a tour with McGregor's picture on his drum skin.

Luckily, the Scottish star was more flattered than frightened - and became a big fan of the Bottlemen's scrappy, infectious album.

And so, he agreed to star in the band's new video Hourglass - even singing the song a capella for good measure.

"Working with Sir Ewan was one of the funnest things I think I'll ever get to do," said McCann. "He's the most interesting and interested guy I've ever met. He's just [expletive] brilliant, a total gentleman.

Watch the video on YouTube - but beware of the strong language.
