THE White Stripes frontman Jack White insists performing live in front of his adoring public is just a case of "getting the job done".

The morose BLUE ORCHID star may be raking in a fortune, but he claims his moody image is simply because he is bored stiff on stage.

He says, "I'm just trying to get the job done.

"I don't laugh and smile because I'm not having a good time."
