Notes: This piece would appear to break up into two subfamilies, "Dear Companion" ("I once did have a dear companion") and "A Fond Affection." I tried to separate the two -- but when I saw the incredible mixture in Randolph, I gave up. - RBW
It's also getting harder to distinguish "Columbus Stockade Blues" from this song. We use the "Columbus Stockade" line as a marker, but several versions of "Dear Companion" overlap heavily with that song in lyrics. - PJS


Thanks, Mudcatters, you've come up with goods again.
