Single on Columbia January 1963 by Australian singer, dancer and actress (1944-2021) born to Sydney theatrical figures Buster Noble and Helen de Paul.
Patsy Ann Noble was a teenage star of national TV pop show Bandstand and was signed by His Master’s Voice for a number of singles of which Good Lookin’ Boy was the most successful.
After moving to Britain in 1962 she released further singles on EMI’s Columbia label without commercial success. However, from childhood she had appeared in theatrical productions in Sydney, and in Britain she was increasingly seen in cinema and TV acting roles. Her acting career flourished from the mid-60s in the USA where she became known as Trisha Noble.
