Since the UK chart began in 1952, there have been 33 songs that have reached number one two in a different version. I have not included songs that have been re-issued by the same act, so Bohemian Rhapsody and Last Christmas for example have not been included. These are songs in a different version usually by a different act albeit some may have a slight lyric change but are predominantly the same song.
