Big Tim,
I got Hall and MacGregor's "Inverey" from iTunes and posted the entire lyrics (complete with some spelling errors, I'm sure) in this thread:
The Baron o' Brackley / Inverey
so that people looking for the song under the title "Inverey" could find it.

Their last verse does refer to what I heard as "the woods o' Glenn Tower." I definitely do not hear another "n" as in "Glenturner" or "Glentanar." He* certainly sounds like he's singing "Glentower" or "Glentaur," but I don't know where that is or how it's spelled.


*(I think the singer is Robin Hall, but I'm not sure.)
