Oaky, I just wasted some more time, but that's fine.
Here's the abc of the tune.

X:1
T:The Lass With A Delicate Air
C:Michael Arne (1740-1786)
I:abc2nwc
M:3/4
L:1/8
K:E

But this doesn't really show how the words fit with the notes. For example the word "delicate" is sung over the 6th, 7th and 8th measures from the end of the tune.
