I play mostly for my own enjoyment and my song circle. They've always been kind. As I practice, my wife will occasionally say either "that's good" or "Why do you like that song?" which I take to mean "that's bad." She says that about Greensleeves and Danny Boy, which I'm the first to admit have both been done to death but I still think are two of the greatest tunes in the world.
Incidently I just learned "Lorena" and sang it at the last song circle, but to ease the 21st century listeners, I left out the last half of one verse ("But then, 'tis past, the years are gone...") and the first half of the next one ("The story of the past, Lorena..."). It doesn't make much difference to the narrative. I play it in "G" which is a little high for my voice but still a fairly normal key. I'd like to hear your banjo solo, Charlie.
