I wouldn't count Jumbo as that was not recorded to be issued as a cast recording. IIRC, AEI announced that it would be issuing those broadcasts on CD, 50 or 60 (or more) years after they were heard on radio, but never did.
The Smithsonian Naughty Marietta, a cast recording of a Smithsonian concert, was issued on LP by Smithsonian. I believe it was announced that Harbinger would be reissuing it on CD but I think that hasn't happened. The Smithsonian Rose-Marie, also a cast recording of a concert, was never issued by Smithsonian. |
