First question: who the heck is Helen Shapiro?
She was a British singer who was 17 when this was filmed. She had a string of hits in Great Britain in the early ‘60s and had an unusually mature and powerful voice for someone her age. At one point she toured with the Beatles and apparently they liked her as they agreed to perform in a somewhat hokey routine.
She sings her song “Look Who It Is” with John Lennon, Ringo Starr and George Harrison lined up with their backs to the cameras.
First John turns to face her, then Ringo puts his head on her shoulder before George falls to his knees to plead his case.
