The only blues song that comes to mind is Lowell Fulsom's "Lonesome Christmas", which I haven't heard in years. So, not sure that has the correct lyrics. It's not quite what you'd find on Prairie Home Companion, though, since it's a bass-heavy Chicago blues.

It may be a tune by The Seldom Scene, the house band for the radio show and very good at bluegrass. Hope this helps.
