This September, Jack White performed at a fundraiser called Another Day, Another Time: Celebrating the Music of Inside Llewyn Davis.

At the benefit concert, White performed, We're Going To Be Friends, a song from his time with The White Stripes.  Along with White's guitar and vocals, the performance features a double bass, banjo, and fiddle.

Showtime will air the concert next week.

Inside Llewyn Davis is a Coen Brothers film.  It will get a limited release in the United States on Friday, December 6.  Mumford & Sons front-man Marcus Mumford contributed to the movie's soundtrack.  Mumford also performed at the fundraiser.

Mumford has another connection to the film.  His wife, Carey Mulligan, stars in the movie.
