Back in 2015, Gene Deitch's words about his Tom and Jerry cartoons was the subject of a Cartoon Research post, used to coincide with the release of the "Tom and Jerry: The Gene Deitch Collection" DVD. Reading it again, there was a part that stuck out to me.
"What I couldn’t tell anybody at the time is that I brought my own Ampex 1/4” tape recorder into the studio, and recorded the orchestras myself, with little more than a volume control and only two microphones, all my own property! The engineers here thought I was crazy, but I got brighter results than they did. (They had only one-channel mono recording. I recorded all the tracks in stereo. Stereo did not exist here at all in 1961! I also created all the sound effects at home, except the sounds Tod Dockstader made, and sent me on quarter-inch tape!"
So it appears that the audio for the cartoons were recorded in stereo, but the release prints were in mono. I'm wondering if these original audio elements are still out there, or maybe they just don't exist anymore.
