Here is a web site that gives a detailed description of the BBC Programme "Time and Tune" from 1972. It identifies the song* as SLEEPING BEAUTY, and gives the first 2 lines. The editor remarks: "To the best of my knowledge, no recordings of this unit have been kept in the BBC archives."

* That is, the song initially requested in this thread. I wish we could keep discussion in each thread limited to one song only, to avoid confusion.
