The Rock Flowers were a "real" girl group that released two albums in the early 1970s. Mattel made a line of dolls for the act, blurring the line between Barbie and the Archies, which came with colored 45 r.p.m. records. The girls could stand on the records as they spun on your turntable, playing tracks like "Your Music N' My Music" and "Mixin' Matchin' Day."
