Also, I have a pretty big collection of 70's country (and rock as well, just about everything that appears on my music quiz is something I actually own). Let me know if there's anything else you want and I'll put it up here.
This is the most 'acoustic' of the three that I have and sounds closest to the one you're looking for (I hope!).
This one and #3 are super-similar, and one of them is the one you've heard already last nite (but I'm not sure which one it was). They both sound like steel, but I put 'em on here just in case. The differences are minor between 2 & 3 anyway.
