Thanks for the Punch link, Joe - I didn't notice it before posting the above. It's interesting that we see it (however so vaguely) in the context of the 1920 miners' strike when Honor Goodheart's grandson attributes it to his grandmother in the strike of 1926! At least this gives us an earlier date than Johnny Collins for the logs to burn sequence.

Somewhat confusingly, a website Here sources the text given by Graves (The White Goddess, 1961) to E.M.Hull's Poem Book of the Gael - I've been through the e-version to check, but don't think it does!

Other versions on-line include: This and This; and This brings it back to Dartmoor!

I might add that before coming up with tune we use now (see link in my first post of today above) I used to sing the Graves text (sans chorus) to the morris tune of Idbury Hill (aka London Pride). I only stopped doing this when I found Idbury Hill fitted Kipling's Puck's Song rather better, which meant coming up with another melody for Logs.
