The two performer-songwriters aligned for the 2010 album, which features songs written by John and Russell, as well as collaborator Bernie Taupin and solos by John and Russell.

Cameron Crowe directed the documentary that promises an inside look at John's creative life and is described as "an extremely candid portrait of one of the world’s most treasured artists and performers, and his extraordinary journey of the heart – one that sent him to powerfully reclaim and reinvigorate the life and musical career of Russell, to whom John hadn’t spoken in over 38 years. 'The Union' is a captivating and exhilarating real-life experience of musical creation and generosity."

"The Union" will premiere April 20 at the North Cove at the World Financial Plaza. The Tribeca Film Festival is scheduled to run through May 1. John will offer a free concert following the free outdoor screening of the film that evening.

The film features appearances by producer T-Bone Burnett, lyricist Taupin, Neil Young, Brian Wilson, organist Booker T. Jones, steel guitarist Robert Randolph Stevie Nicks and Don Was.

John is a five-time Grammy Award winner and Academy Award winner for "The Lion King." He has written the scores to the Broadway musicals Billy Elliot, The Lion King, Aida (Tony Award) and Lestat. A new film inspired by his life, penned by Billy Elliot collaborator Lee Hall, is also in the works. John's numerous albums include "Goodbye Yellow Brick Road," "Tumbleweed Connection," "Captain Fantastic and the Brown Dirt Cowboy" and his self-titled 1970 album.
