Yes, was Renaissance that I was thinking about. There are CD`s of the "BBC Sessions" and most of the tunes I remember seem to have come from no later than 1978. "Take 3 Girls" starred Lisa Goddard as violinist Victoria, Susan Jameson as actress Kate, and Angela Down as art student Avril. The series ran from 1969 to 1971 with four more episodes being recorded in 1982 under the title "Take three women" with the same cast.
