5/19/74 tree?

[Jim Powell]

We just made a composite complete SBD of Portland 5/19/74, consisting of MSR
> R > D > CD with the 6 tunes from the first set (Jed through El Paso)
missing on most circulating SBDs supplied from MSR > C > D.  The mix on
these six tunes is weird, with the vocals very low in the mix during several
tunes.  I have the impression that maybe something like this is already in
circulation but if not I'll be glad to seed a tree if someone will
administer.
