Glaswegian glamourdolls (matching polka-dot dresses, colorful hair streamers, blood-red lipstick) Jill Bryson and Rose McDowell do all the vocals, songwriting and guitar work; seven sessionmen (and an orchestra) provide the bubblegummy electro-pop backing that makes lightweight creations such as “Since Yesterday” and “Secrets” so unavoidably charming and catchy. Capping a brief but colorful career, the duo went their separate ways in June of 1986.
