Hi there.
I'm on dodgy ground here, as this is a remembrance from nearly 25 years ago.
But i hope it helps.
When the quadrophonic debarcle was going on in the late seventies. Binaural sound came to the fore in the shape of Ambisonics. (since developed as a surround format)
Sony and CBS had their rival qaud. systems SQ and QS (they were seperate companies in those dark days). The BBC flirted briefly with a system they called matrix H.
From these experiments, I'm sure that Michael Gerzon was around at the time, they developed a two channel system for reproducing three dimensional sound called Ambisonics which had it's basis in binaural recordings.
In fact i can remember being the recording tech on The Archers which was recorded binaurally and using an Ambisonic encoder. Certainly it was broadcast as such even into the nineties, though not sure now.
The placement of sound was such that the standard BBC library effects could not be used, and had to be recorded specially for that programme. Including studio techs kneeling at the feet of the performers imitating dogs panting to get the "height" correct on the recording.
For full surround, you needed an Ambisonics decoder, but I'm pretty sure the system worked well enough through headphones etc as binaural does.
Anyway, I could be barking up the wrong tree. but it would be worth checking out BBC released classical music as i'm sure they were recorded binaurally for a while.
There is a site dedicated to Ambisonic recordings (in that they differ from Quadrophonic) at

Sorry, haven't worked out how to do the "here" thing yet!
There are links on that site to the York University Technology Group who have a dedicated site to 3-D audio (including Ambisonics and binaural)
Meridian, the Hi FI manufacturer was also involved, they have got Ambisonics written into the DVD A specification through Meridian Lossless Packaging. So there is a chance that Ambisonic (and by default) some of the earlier "stereo only" soundtracks becoming available by default.
They are a very helpful company and may well be worth a call to them.
As I said, I could be barking up the wrong tree, my memory of those days is a little hazy, especially as I didn't have much interest in surround in those days. I could therefore be wasting your time, but, of course it may give you a link to what you are after.
Good luck, good hunting.
