"A Moment Changes Everything" is the first single taken from David Gray's ninth studio album Foundling. The song was at one point scheduled to be included on a re-release of Gray's previous album Draw the Line, together with other unreleased tracks from that album's sessions. Promotional singles of "A Moment Changes Everything" were released to radio stations with the text "brand new single A MOMENT released 31st May 2010, Re-Release of Draw The Line with bonus material 7th June 2010" on the sleeve. The re-release was eventually withdrawn in favour of a brand new studio album, with "A Moment Changes Everything" being released as the lead single.
