LOS ANGELES -- Jamie Cullum, whose "All at Sea" has broken the British jazz singer and pianist into the mainstream, is about to break a little further.

For the follow-up and second single from Twentysomething, the self-taught musician is releasing his version of Radiohead's 1995 single "High and Dry."

"As well as writing songs, jazz musicians are always trying to take material and do new things with it," Cullum said. "The notion of a standard is something that is 50 years old to most people. I only discovered [what are considered] old songs about three years ago. An old song to me is 'High and Dry,' which is a song I grew up with. I was 14. If you could play it on the guitar, you could kiss all the girls."

Cullum plans to shoot a video for "High and Dry" later this month. "We've got a very strong idea, very mysterious, very different, so I wouldn't want to give it away," he said.

The singer will work with a director on the clip, although he hopes to direct his own videos soon and eventually get into movies.

"I studied film for three years -- I got a film degree -- so I'd be much more interested in getting behind the camera than in front of it," Cullum said. "It'd be weird stuff that no one would want to watch."

One thing millions of people surely will watch is "Genius: A Night for Ray Charles," a concert tribute to the late singer that'll be broadcast October 22 on CBS. Taped Friday in Los Angeles, the concert featured Cullum singing Charles' "Hallelujah, I Love Her So." "This is the pinnacle of my career," he said of the show, which also included Stevie Wonder and Usher (see [article id="1492118"]"Jamie Foxx, Usher, Mary J., Stevie Pay Tribute At Ray Charles Memorial Concert"[/article]).

Cullum, who has a new song on the "Bridget Jones: The Edge of Reason" soundtrack, is in the middle of a North American headlining trek.
