Hi, Open Mike. That's the same performance I linked above. Music starts after one minute. It's beautiful singing and a beautiful melody on a dismal theme.

Guest Ron Mullennex is perfectly correct. Google Maps shows a Blue Mountain in Pennsylvania, and there's a Blue Mountain Resort at Palmerton. Blue Mountain seems to be a long ridge, as is typical of the Appalachians. There's a reason why the geologists call that enormous crumpled zone "the Valley and Ridge".

That abc file upthread needs work, but I think the melody's worth it.
