I cant remember the title or the singer,but I tjink some of the words were, oh Allison please if im not mistaken your heart has taken a downward ride, he came along and burst your pretty balloon, now your heart sings a song thats really way out of tune.
don't know what the song is, but it's not the one by Elvis Costello (which is an absolutely fabulous track, but doesn't have the lyrics you've quoted).
