The documentary about last summer's trip screens at 4 p.m. today at the Paramount Theatre as part of SXSW Film. You might see Austin musician Ephraim Owens, who was on the tour, and the Austin High School Band, who backed Mumford in Austin, in the film. That screening will be followed by an acoustic performance by band members. Then the whole shebang heads over to the LBJ lawn at the University of Texas for an encore screening and a concert. That event is free with RSVP, sponsored by MySpace. When we checked Friday, the RSVP list was full.
