Thanks, all.

I don't think it's Libba Cotten I have in mind, as I never saw Libba Cotten perform, and I think this is someone I actually saw in person.

I don't think it's Bill Staines I have in mind, because I don't think I knew who he was in the late 60s or early 70s.

I don't think it's Dan Seals, or Lefty Frizzell, and I'm sure it's not John Dady - I regret to say I've never heard of John Dady.

Well, maybe it was all in my imagination, or maybe it was Bill Staines and I've just got the wrong decade.

Art, do you know that batting righty and throwing lefty is by far the rarest of the four possibilities? Rickey Henderson did that, but he's about the only long career non-pitcher to do it in a long time.

At the risk of going way off-topic, I'll record here that I throw overhand righty but underhand lefty - so, in baseball I'd be a right-handed pitcher, but in ten-pin bowling I'd be a lefty.
