Crowe's "The Union" Premieres at Tribeca

GRAND UNION: Cameron Crowe’s documentary about the making of Elton John and Leon Russell’s album, The Union, will have its world premiere on opening night at the 2011 Tribeca Film Festival, April 20 (4/20, get it?). Crowe decided to film their collaborative process, from writing through recording. "As a longtime fan of both artists, it was a pleasure to spend a year filming their collaboration,” said Crowe. “We can't wait to show it to one of the greatest audiences in the world, the Tribeca Film Festival.” (3/3p)
