One of the best screw ups I ever heard was Nick Dow singing a song called 'Seven long years' - don't bother asking for the words, had my song book stolen a few years ago, never did replace all of them, but if anyone knows the song I mean, can they please post! - Now Nick is not a slim gentleman, and managed to paste two lines together, coming up with 'Seven long years since I saw my Willie-o'.OK 'Spaw, do your worst with that one!!
