This version of ‘Dear Tobacco’ is from the Anne Geddes Gilchrist collection, collected from William Docker in Westmorland, England. I can’t find a date for it, but John Offord (always a good source of knowledge) says it is “not a polka. Polkas came later in the 1840’s. It is a type of reel which is found in books from the 1700’s. These tunes, with patterns of 4 semi-quavers [written out here as quavers] were only played in Scotland or Northern England”. This version is also in Dave Townsend’s English Dance Music book, Volume 2.
Here are the dots for the tune:
I’ve written out a seperate chord chart below (with an extra Bm chord, apologies!) with an alternative, slightly crunchier version that doesn’t resolve at all.
