Some of his earliest (and most memorable performances) came while portraying Bertie Wooster in the series Jeeves and Wooster based on the popular P. G. Wodehouse novels. Here's my personal favorite from that show:
Then there's the time that Bertie tries to figure out how to master "Puttin' on the Ritz"
He also once demonstrated his songwriting skills.
Here's his performance of Wild Honey from his latest CD. The amazing thing to me is the decision to record the entire group live in the studio. I think that adds a lot to the production. Hats off to Hugh Laurie for bringing the blues back to life. Enjoy!
