It is Kate Bush - Womans Work from the album The Sensual World... I am going mad at the moment trying to find out the piano music played when Simon was deciding on his final 7!!!! cant seem to get any answers.............
Try and look for this piece I think when sharon was telling her group they was staying esp the lady from the chicken factory a piece of music was playing it sounded classical I love this piece I think its mark isham "Flames" its also played in the film crash but I could be wrong
