Kerry Martin (real name Cecilia Sparrow) was signed to Parlophone by George Martin in 1958.
She made one record: Stroll Me / Cold Hands, Warm Hearts, though it may not have got beyond the demo stage.
She appeared in the very brief touring stage version of Six-Five Special, with John Barry & Adam Faith, but left the business in 1960 when she married the legendary QC George Carman (they were divorced in 1975).
