 According to Bob Geldof (qv)s autobiography, (which also mentions  the Supergirl body mould), when filming the scene where the groupie  starts sucking Pinks fingers (before he smashes up the room in "One  of My Turns"), Jenny Wright (I) (qv) couldnt get the scene right.  She asked director Alan Parker (I) (qv) what her motivation was  for the scene, and he replied, "money". She got it right on the next  take.
