Carnegie Hall Concert....Columbia set SL160
Broadcast recordings....Columbia set SL180
From the liner notes...
These recordings are made from "air checks" of late evening broadcasts from all over the country. Most of the original discs were taken off the air by a fan named Bill Savory, now a Columbia records engineer, who also did the remarkable editing job which produced these final master tapes. The final result is the most authentic original-Goodman sound ever captured on record, whether the band was broadcasting from the Manhattan Room of the Hotel Pennsylvania or the Palomar in Los Angeles.
The broadcasts gave us another advantage not possible in the case of the Carnegie Hall album. We frequently had six or seven versions of the same tune to choose from, so there was no need to put up with flagging inspiration or minor flaws.
