Watch Daniel Radcliffe and His 'Brotherhood' Succeed on Late Show With David Letterman

Daniel Radcliffe and his fellow World Wide Wicket employees set up shop over at the Ed Sullivan Theatre on May 19 to perform a number from the Tony-nominated revival of How to Succeed in Business Without Really Trying on the Late Show With David Letterman. The affable talk show host looked pretty blown away as the cast showed off Rob Ashford's impressive choreography with the show-stopping number, "Brotherhood of Man." After the audience responded with resounding applause, Letterman joked to Radcliffe that, "We'll talk it over and let you know about the audition." Take a look at the performance below!
