Caught Up in Smoke on IFC last night. Sadly, the wife put the kibosh on watching the Cheech & Chong marathon they had going on.
I vaguely remember this track from the old LP soundtrack album, which I put onto one of the first mix tapes I made on the turntable as a kid for listening through my boom box at school.
Anyway, great tune by a band called Yesca. Enjoy!
