Legendary band The Who have reached out to their supporters, looking for rare recordings to complete archives as the band celebrates its 50th anniversary with a year long series of events, releases and promotions.

All items, which might include 'rare radio and TV performances, home movies from gigs, extraordinary bootleg material, demos, unusual photos and memorabilia', may be used on the band's 50th anniversary releases, and the fan with the best find will win two VIP tickets for a show on the upcoming tour.
