Yes, she was a girl from Tiger Bay as DtG said. Which reminded me of the film, which was shot in Tiger Bay. You can see some scenes in the trailer.
Tiger Bay (1959 film).
I had forgotten in the 50 or so years since I watched it that its star was actually Horst Buchholz who was apparantly known as "the German James Dean" and went on to appear in several well-known American films.
