Well, I know it's a version of "The Two Sisters," so I crosslinked this thread with the others on that song. You'll find links to countless versions of the song above, but I don't know which one Waterson:Carthy/Rose did. I gather from this page that they have been performing a version called "Bows of London" (click), and I don't think we've had that version posted here.
The estimable Garry Gillard has transcribed the lyrics of all the Watersons songs, and you'll find his transcription https://mainlynorfolk.info/frankie.armstrong/songs/thetwosisters.html here (click).
Hope that helps.
