Take a listen to the intro to 'Roxanne' again... A little way in theres an awful 'chord' played on the piano, totally out of place - followed by Sting laughing... I'm told the session was recorded in a very small studio with a piano still in there. It was so cramped that Sting accidentally sat on the exposed keyboard whilst recording, and laughed when he produced the aforementioned bum note... No idea if this is true or just an Urban Legend, but it certainly explains what is an otherwise totally out of place piano note !!!
