Hi Peter. Thank you for your reply and I apologize for the belated acknowledgment-- I forgot to check back until now! I believe there is always the chance that a collector like myself could stumble upon a set of these discs in an unlikely place. I also believe that it's possible to find them cheaply at a yard sale or used record store, so I just keep looking. To comment on your post above-- it would seem that the ABC archives should still have the original (master) copy of these recordings since Colin Simpson was representing the ABC and made many of the recordings for airplay on national radio. There are still a few folks around the globe who are knowledgable regarding the use of "wire" recording devices-- so it shouldn't be too difficult, nor that expensive to transfer the original wire into a digital format. Then, everyone could enjoy and learn from these recordings. I've heard Manikay's sampling of the album set and what surprises me is that tracks on the discs are only a small sampling of a large body of wire recordings. There is a webpage dedicated to the AASEA 1948 which contains two streaming radio programs-- one is from the original ABC feature which aired around the time of the broadcast, the other is a recent revisitation. These are much, much better audio than the Manikay mp3's. Below are links to cut and paste into browser--most likely everyone on here has already heard the show, but here they are again.
