Pop star Nick Jonas is wowing crowds as J. Pierrepont Finch in How to Succeed in Business Without Really Trying at the Al Hirschfeld Theatre, but on February 13, he took his performance to a more intimate setting. Accompanied by just a piano, Broadway’s newest window washer stopped by WNYC’s Soundcheck to sing a swoon-worthy special arrangement of How to Succeed’s signature song, “I Believe in You.” Check out Jonas’ new rendition of this classic tune, then see him in person on Broadway.
