What I know about these recordings..

Both tapes are from Les Kokayīs original FM broadcast stereo 
recording, and they're have better quality then the circulating material, including the commercial "Studs Terkelīs Wax Museum" boot.

Lineage & Notes:

Riverside original lineage:

Original Analog Stereo Tape from FM Broadcast > DAT > CDR > mkwact > 
MKW. Then goes transformations.

Studs Terkel:

Original Analog Stereo Tape from FM Broadcast > DAT > CDR > mkwact > 
SHN

Please note, that there are significant cuts of the interviews as 
compared with the commercial boot release "Studs Terkelīs Wax 
Museum". These were operated by the radio station, in order to fit 
the tape into an one hour broadcast scheme. Due to the same 
reason "Who Killed Davey Moore" is left out completely.
