In my childhood, when visiting my grandparents in Eastern Oklahoma, I sometimes heard a couple of old timers playing Blues--one feller on Guitar, the other feller on an old teardrop Mandolin. They lived in a community off to itself which was not an actual town. (I didn't understand why until years later when I realized that it had to do with segregation.) I just knew that they were a couple of fun fellers who'd sometimes be down at the river fishin' at my Grandad's favorite spot. They were very good. That's where I first heard real blues. They could really make those strings talk. I asked the Mandolin feller about his baby Guitar, & he thought that was the funniest thing he'd ever heard & went right into "Baby Guitar Blues" which he came up with on the spot. I asked him to sing it for me whenever I saw him.
