Sanna Nielsen won the right to represent Sweden last month - and the song is one of the favourites to win the whole event in Copenhagen, although questions have been raised regarding the lyrics. The grammatically incorrect "Undo my sad" lyric has undergone a slight revamp. Fredrik Kempe penned the song and decided to make a slight changes to the lyrics. The lovely Sanna will now sing "Undo my sad love" as the last line in each chorus. You can listen to the new version here. Will these changes improve Sanna's changes of winning?
