Woody Guthrie's land is your land, the folk legend's daughter says, figuratively, to Billy Bragg and Wilco in an upcoming documentary.

The political Brit folk-rocker and the alt-country band recorded 1998's Grammy-nominated Mermaid Avenue and last year's Mermaid Avenue Volume 2 — two acclaimed albums of songs using previously unpublished Woody Guthrie lyrics his daughter discovered in her father's notebooks.

"Man in the Sand," a behind-the-scenes portrait of the making of the first album, which will include five unreleased tracks, is due March 27 on Rykovision, the film division of the Rykodisc record label.

The DVD and VHS release centers on Nora Guthrie, Woody's daughter, who uncovered notebooks filled with words Woody scribbled down throughout his career. She then recruited Bragg and Wilco to write music for the lyrics and record the songs.

"Man in the Sand" also documents the contributions singer Natalie Merchant and guitarist Corey Harris made to the album, and it includes Bragg's original Mermaid Avenue demos.

Woody Guthrie, who wrote the perennial classics "This Land Is Your Land" and "Do-Re-Mi," died in 1967.

In other Wilco news, drummer Ken Coomer has left the band, according to its spokesperson at Reprise Records. A statement explaining his departure has not been released.

Wilco's remaining members are in a Chicago studio, fitting recording sessions for the as-yet-untitled follow-up to 1999's Summer Teeth in between singer Jeff Tweedy's solo tour dates (see [article id="1438963"]"Jeff Tweedy To Debut New Wilco Songs On Solo Tour"[/article]).
