Thanks, Jim! I followed your link and bought a copy from Amazon. Sure enough it has this song in it, but sadly not another one that was in the same booklet, BBC Time and Tune, Autumn 1972, which had the words:

'Then a prince shall awaken the fair princess, his lips on her brow he will softly press, they'll live ever after in happiness, so dry those tears.'

I'd still love to get hold of a copy of the actual Sleeping Beauty booklet.
