Ansermet's Saint-Saens Third was indeed on CD in several different
incarnations. I don't recall if it made the Ansermet box set that Decca
put out sometime ago, but I would be surprised if it didn't. I had a
London 'Weekend Classics' issue that I bought for $3.99. I then did my
own LP transfer and liked it better. I'll gladly send you a copy Joe.
Contact me off-list, if interested.
