STAGE TUBE: A Phantastic Pairing- Josh Groban & Sierra Boggess Duet on 'All I Ask of You'!

Josh Groban, who will perform on Sunday night's Tony Awards, is busy promoting his new album, titled "Stages," in New York City. Released earlier this spring, via Reprise Records, the album is a collection of some of the greatest musical theater songs of all time, which Groban describes as "gorgeously arranged songs that have stood the test of time," and which he was drawn to because of their combination of "incredible melody with an incredible story." Below, watch as he stops by #PandoraPresents to perform "All I Ask of You" with Sierra Boggess!

Recorded with producers Humberto Gatica and Bernie Herms in both Los Angeles and London's Abbey Road (with a 75-piece orchestra), Stages features songs from LES MISERABLES ("Bring Him Home"); Rodgers & Hammerstein'sCarousel ("You'll Never Walk Alone"); Stephen Sondheim's Sunday in the Park with George ("Finishing the Hat"), Sweeney Todd ("Not While I'm Around"), and Into the Woods ("Children Will Listen"); The Fantasticks ("Try to Remember"); A Chorus Line ("What I Did For Love"); Andrew Lloyd Weber's Phantom of the Opera ("All I Ask of You"), The Wizard of Oz ("Over the Rainbow"), and others.
