Dear Lynn,
Sorry for the misattribution to the Oscar Brand show. When I first saw the clip some time ago, I had been clicking around various clips from Oscar's show, thought I recognized him from the severe angle from the rear in the clip, and didn't pull down the rest of the description, which clearly indicates the show. Probably the first time in history Oscar Brand was mistaken for Robert Preston. That's how wrongful convictions happen. But it drew out your lovely reminiscence about the show, so no harm, no foul.
The "irish tape" is the open reel tape referred to in the posting by John Wilford that "mysteriously made it to Ireland" before you, as you said.
I would be happy to supply copies of the two tracks from Time/Life. My name is in the "from" line of this posting, and if you google it, you can get my law school webpage (I teach law) which will give an e-mail address, if you want to tell me how to get them to you (digital e-mail attachments would work).
Best,
DMR
