Wikipedia

  1. Proof

    Proof is a song by English band I Am Kloot. A demo version of "Proof" was released in 2001 as a B-side on the single "Morning Rain" from the album Natural History. This version is also included on the compilation album B from 2009. In 2003, the song appeared on I Am Kloot's self-titled second album. Even after the making of a video for "Proof" (by Krishna Stott, featuring Christopher Eccleston), their then record label, Echo, subsequently shelved the release of the single. "Proof" was released on 21 June 2004 as a download-only single, but it did not receive its intended, full release. Finally, in 2010, a remodelling of the song was produced for their fifth studio album, Mercury nominated Sky at Night. This new version of "Proof" was released as a download-only single on 6 September 2010 – the second single, following "Northern Skies". The 2010 video for "Proof" (the old video with the new audio) was also released in September 2010.
