Marine Girls were a post-punk group from Hatfield, Hertfordshire. The group was formed in 1980, by two sixth form school friends: Tracey Thorn and Gina Hartman. Originally, Thorn just played guitar and Hartman was the lead vocalist and percussionist. Thorn overcame her shyness and started singing too by the time they started making records. They were later joined by Jane Fox on bass and her younger sister, Alice, on joint vocals and percussion.
