VIDEO: Josh Groban & James Corden Sing 'Copyright-Free' Medley of Tunes!

Later in the show, James asks Groban about pursuing his pilot's license, and fellow guest Justin Long talks about the idea of becoming an Uber driver and what research he's done. Watch the clips below!

Yesterday it was announced that Grammy-nominated multi-platinum recording artist Josh Groban will make his long-awaited Broadway debut as 'Pierre' in NATASHA, PIERRE & THE GREAT COMET OF 1812 on Broadway next Fall.

The singer, songwriter, and actor's multi-platinum albums and DVDs have sold over 30 million worldwide and he is the only artist who has had two albums appear on the Top 20 Best-Selling Albums list of the past decade, according to Billboard.

He has appeared in the feature films Crazy, Stupid, Love, Coffee Town, and Muppets Most Wanted, as well as on NBC's The Office, FX's It's Always Sunny in Philadelphia, and CBS' The Crazy Ones. Last year, he hosted ABC's unique singing competition Rising Star. Groban has released seven studio albums, 2001's self-titled double-platinum debut, 2003's multi-platinum Closer, 2006's double-platinum Awake, 2007's quadruple-platinum Grammy-nominated Noel, 2010's platinum Illuminations, and 2013's All That Echoes, which debuted at No. 1 on the Billboard Top 200 chart, giving Groban his first No. 1 debut and third chart-topper. The album and its intimate "In The Round" tour earned Groban some of his best reviews to date. In April, Groban released Stages, a collection of some of the greatest songs from musical theater. The album has been nominated for a 2016 Grammy Award for Best Traditional Pop Vocal Album. In February, Groban will release a CD/DVD package, entitled Stages Live, featuring performances recorded at the historic Los Angeles Theater in downtown L.A. for his all-new PBS special Josh Groban: Stages Live. In July 2016, he will embark on an extensive North American tour to support Stages, entitled "Josh Groban: On Stage."
