Technically, I think that this should be listed under the Memphis Recording Service, rather than Sun proper...Or maybe Memphis Recording Service/Sun...
Surprised that McCartney didn't buy it, seeing as how he already has Bill Black's stand-up bass & other things...
"Re-pressing" is actually a misnomer, since these recordings were actually cut into the lacquer of the disc itself. They originally never got to the pressing stage in the first place, since they were personal recordings only.
