"Summer Moved On" is a song by A-ha which became their first single in more than six years. The album Minor Earth Major Sky was released in the UK on 22 May 2000, having been released in much of Europe on 27 March. The song was originally hastily written after A-ha agreed to a one-time reunion at the Nobel Peace Prize concert in 1998. There had been a lot of bad feelings between the band members, and each was hesitant to reunite.
