Well, I lost my notes. Can someone please identify the version of "Some Tyrant has Stolen My True Love Away" (Roud 587 that contains the following stanza:
The bugle shall speak and the serpent shall sing
There'll be instruments of music for to make the valleys ring.
Oh the huntsman he'll holler and the hounds make their noise
For to fill my love's heart with ten thousand bright joys
I can find this on the internet among the lyrics of songs of a CD, but of course there is no hint as to the source of this version.
