Not sure exactly when Boris made the recording, but it was sometime in the fifties. Children, of course, were his biggest audience at the time, since the old Universal horror flicks were being played on TV at the time, and this gave his biggest fans a chance to see the real Boris.
Here are some sites I found. The first is a list of some of Rathbone's recordings including sound clips of Peter and the Wolf. The entire site, by the way, is great, a comprehensive guide to everything Basil:

http://www.prokofiev.org/catalog/workessential.cfm?WorkID=80Since I got my record set, done by Mr. Rathbone, in the mid '40s, then I guess that mine are the oldest. I don't know when it was produced, though.
Many thanks for the links!
That's it, that's it, THAT'S MY RECORD SET, the one with the dark green background ! :-)
I have a different TUBBY THE TUBA, though.
