The best surprise was a very pretty singer named Billie Davis. She was also unknown to me but not to British fans of pop as she still performs in shows with her friend Jet Harris. I got an immediate crush on this girl and she was just 18 years old in this film. She is now 61 but still quite pretty as I discovered from her fan site. Try and get her CD of her best stuff from her Decca years.
Many great performances make this a snapshot in time of the British invasion pop scene and well worth your time.
