No relation to Gerry Marsden, Beryl began her career by acting as an occasional singer with several of the Liverpool bands including Lee Curtis & The All Stars and The Undertakers. She embarked on a solo career in 1962 and, under the guidance of manager Tony Stratton-Smith, signed with Decca the following year.

After two singles for Decca she moved to EMI's Columbia label in 1965. Three further releases undeservedly sank without trace.
