OAITW planned a studio album, and at one point we assumed these sessions were part of that plan. But it seems that the studio album may have been attempted earlier in 1973, so we just are not sure. We now believe that this session involved sweetening of some live tracks.
"Vassar's Tune" is from the paperwork. It is likely to be "Kissimee [sic] Kid" or "Lonesome Fiddle Blues" --played two nights before-- or something else. Also note there was a song with words called "Old And In The Way" and an instrumental "Old And In The Way Breakdown" - we follow the paperwork in listing it as the former, but it could be the latter.
