The Little Ladies
From the British TV series Rock Follies / Rock Follies of '77 (1976-77).
Each series had a soundtrack album featuring the group's songs (masterminded by Roxy Music's Andy Mackay) and the second spawned a top ten hit single, "O.K.?". Many of the songs were sardonic commentaries on the music business. The hit's B side was the amusing "B Side" in which the sidelined former lead singer of the band laments that's she's now only allowed to sing B sides. Naturally.
