Prior to the show will be a free screening of Cameron Crowe’s The Union, a documentary in which John is the star subject. The film captures his album writing and recording process, and is scheduled to be premiered at 8:15 p.m.

“It’s a special opportunity to open our 10th Festival in this distinct and unique way,” said Jane Rosenthal, Tribeca Film Festival co-founder. “Not only are we inviting the community to join us for the world premiere of Cameron Crowe’s film ‘The Union,’ but to have Elton, whose music transcends generations, perform after is an extraordinary gift.”

The movie screening will take place rain or shine, while the concert is subject to change in the event of inclement weather. Should it rain, John will not perform from the outdoor stage, but instead his performance will be screened live on the outdoor screen at the North Cove at the Plaza, and via tribecafilm.com.
