 Some characters return (or are lookalikes) of characters in Rock  Profile. These include: The "Kelsey Grammar school" teacher is also  Kula Shakers teacher. Eugene (see series 2 deleted scenes) looks a  lot like Art Garfunkel. The "I was Molly Sugdens bridesmaid" couple  look like the couple outside the Prodigys house Bubbles looks and  sounds like Shirley Bassey.
