The Mom of Mimsey (Mumsey, I reckon that would be) just sent me some email asking about a song by this title. Clues she supplies:

"The first line is 'When It's Darkness on the Delta'; second line I can't remember (except for the music...I remember the tune to all of this.) Third line is a repeat of the first and then 'Let me linger in the shelter of your arms.' The middle part of the song starts out 'workin' on the Levee.' Now that's all I remember of it."

Got any takers on this one?
