Daniel Radcliffe and the cast of Broadway’s How to Succeed in Business Without Really Trying stopped by The Late Show with David Letterman yesterday and performed a showstopper that proved Radcliffe is a true song and dance man. For some reason, CBS hasn’t made the performance itself embeddable. That’s a shame. Click here for the full episode on CBS.com and catch Radcliffe and Co. at 38:20. I was a bit worried when the choreography at 39:37 seemed inspired by Human Centipede, but it kicks into high gear by 39:50 and Radcliffe is spinning, doing a handstand, and otherwise seriously hoofing it.
