To Dick Greenhaus: You will note that I cleverly spelled Copper with only one "p". That is why I didn't find that one, I guess.
I can't explain how I missed the other one. I didn't try "moonshiner" alone, thinking that would yield too many hits, so I tried various phrases in the song containing that word.
To Jon W: Thanks for the lyrics and the name of the artists.
To Hellen: I am embarrased--I never did notice that they are so similar although I know both of them.
Thanks to others for some songs I wasn't aware of.
