Yup, it is an old gospel thing. Perhaps Wade Mainer, or similar. I think I heard Dillon Bustin do it at a party a long while back. Been struggling with a very sick parent and the chorus just keeps ringing in my ears. Chorus is something like:

Give me just a little more time lord, Give just a little more time, , Got a lotta things that I want to do, Before I leave this world behind, I'm ready when you call me lord, But give me just a little more time.
