In the episode Andy and Opie Bachelors when Peggy comes over to cook for Andy and Opie one night on the porch she and Andy sing a beautiful song together. Does anyone know the name of the song and who originally sang it?

It was "Down in the Valley"-

Down in the valley, valley so low,
Hang your head over, hear the wind blow.
Hear the wind blow, dear, hear the wind blow.
Hang your head over, hear the wind blow.

(That's the first verse)
