bourgwick, 
wow, i'm pretty sure this is a new, uncirculated 1973 pro video of willie nelson (& sammi smith) at the alliance wagon yard in #austin, served up via the mark pines collection at @internetarchive. can't pin down the date, but willie looking high af & sounding awesome. willie joins sammi smith around 17 minutes into part 1, which flows into his own set.
