This is a haunting lament and Jon says, “A beautiful song about which I know very little, learnt from Maddy Prior. I sang this at my Grandfather’s funeral.” I’ll add that I also know very little and cannot find anything to help. Mainly Norfolk has the lyrics and I’ll note that it only appears on the live CD, ironically titled Tonight The Night. Steeleye have never recorded this in the studio. Anything you can add here will be appreciated as Mudcat offered an impenetrable wall of threads either related to ‘dawn’ or ‘day,’ but not necessarily both and nothing with this title or first line.
