I realize that “Work Tune” is kind of a stretch, because I’m not playing real work songs like “Union Maid,” but I think the blues count, right? Here’s Robert Johnson’s 1936 recording of “Walking Blues” for your Wednesday listening.

Why this one? I like the nervous energy in it, and I like the verse around 1:30:

Worst old feelin’ I most ever had
Some people tell me that these old worried old blues ain’t bad
It’s the worst old feelin’, I most ever had
