'Lost' Beatles concert now a documentary

The Beatles are hitting theaters nationwide, The Associated Press reports.

Recently discovered footage of the Fab Four's first full-length concert in the United States is the subject of a new documentary, "The Beatles: The Lost Concert."

Recorded at the Washington Coliseum on Feb. 11, 1964 to an overbooked teenage audience of 8,000 screaming fans, the 12-song set included "She Loves You" and "I Saw Her Standing There." (The Beatles actually shared the bill with three other acts, The Caravelles, Tommy Roe and the Chiffons.)

The show came just two days after the group's landmark appearance on "The Ed Sullivan Show."

The documentary covers the band's historic arrival in America and includes new interviews with Steven Tyler, Chuck Berry, Mark Ronson, and others.

The film's world premiere is scheduled at Manhattan's Ziegfield Theatre on May 6, and will be in 450 theaters nationwide on May 17 and 22.
