Guest Dave:

Thanks very much for completing it and (probably) correcting some mistakes.

Here is the tune as I remember it, line by line, in solfa (scale is
DRMFSLTdrmfslt, except that there are a lot of accidentals, so make that DRMF4SLTd1r2mf4slt):

m.2.m.d.....S.....
m.2.m.d.....S.....
S.L.T.d.r.m.s.f.L.t...
rmf.s.l.r...
rmf.s.l.r...
rrs...ss4...4.s.....S.....

S...L.T...d.m.....m.....
S...L.T...d.f.......
m.r...1.r...2.m...d.S...
S.4...m.r...L.r.........
S.S...L.T...d.m.....m...
m.2...m.t...l.f.....f.....
d...T.r...d.m.....l...
m.s...f.m...r.d...........

Dots mean continuation for another half beat. The rhythm, as I remember it, is irregular, so I have not tried to divide it into measures.

It is indeed a complicated tune, probably not a folk tune. At a guess, my mother learned it when she was little. She was born in 1908.
