Billed as "The Goddess of Rock", Zenda Jacks (whose real name was Sue McCloskey) was Magnet Records' Glam answer to Suzi Quatro.
Her first single, Rub My Tummy, became a UK radio hit but never made the charts. Two other singles followed: Earthquake and Do You Love Me?. In 1975 she had her own band Stormbringer.
Jacks joined Silver Convention in 1977 after Penny McLean left.
