Gaynor adopted different stage names until settling on Bonnie Tyler. For nearly a decade she and her band performed at pubs and nightclubs all over South Wales.

Bonnie Tyler first entered the pop charts in 1976, with Lost in France reaching the Top 10 of the British charts. The success of Lost in France led Tyler to record her first album in 1977 - The World Starts Tonight.
