Gospel week, day 3: homework... homework... give me a break!

Jackson Southernaires: "Don't Let Him Catch You (With Your Work Undone)" (Songbird, 1973)

Somebody tell me-- did the "don't leave your homework undone" meme start in church and cross over to R&B, or did it come from all of the cheating songs of the day and then get put to use here?
