It runs close to the bone but it's very tongue-in-cheek."'Fields of Gold' singer Sting is also due to record a part of the song, while 'Ali G' creator Sacha is keen to get his friend Madonna involved too.The source added to Britain's Daily Mirror newspaper: "Madonna worked with him for her cover of 'American Pie', when he appeared in the video, and he's approached her to get involved. It will be quite a coup if he does."If the film is successful, there's every chance the song will be released as a single."
