Nope, not the Clutch tune, but thanks anyway!
I did send the band a message on Myspace, so now to see if they reply... It seems that if it was a cover, there'd be something about it on the web that Google could pick up on.
Considering how much, uhhh, "thirst quenching" we were doing last weekend at the river, I'm surprised I was even able to recall that much at the end of a Saturday night.
The other funny thing is that the only reason I figured the band was called Texas Renegade was because they were loading into a trailer with that name on it, but when I went to the website, the guys in the pics don't look like the guys that were on the stage. So...it could have been a borrowed trailer and the guys in TR might just be like "what's this guy talking about"
Oh well. If I find it, I'm gonna try to learn to play/sing it. It has a cool mean rockin' country vibe to it. I'm not a big country fan, but there are songs and artists here and there that I really dig. Of course country has almost as many sub-genres as metal, so there's something for everybody with an open mind.
Edit: the vibe kinda reminds me of Volbeat's "Sad Man's Tongue," which is an AWESOME tune!
