Proof

"Proof" is a song by English band I Am Kloot, and exists in a number of versions released between 2001 and 2010. The song has been released as a single twice in 2004 and then 2010, and has a music video by British filmmaker Krishna Stott featuring the actor Christopher Eccleston. Release 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 production of a video for "Proof" (by Krishna Stott and featuring Christopher Eccleston), their then record label, Echo, shelved the release. "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". This single also saw the release of the original music video with the new audio, again in September 2010.
