Matrix A: CLX 1707
Matrix B: CLX 1708
Rec. in Oct 1931 in Paris, France
The recording date is documented in "The Complete Entertainment Discography, from the Mid-1890s to 1942" by Brian Rust, Allen G. Debus 1973, from which the release date is derived.
Picked up at the weekend what appears to be an unplayed / untouched (till I dropped my fingerprints over it) copy of this amazing condition for a pre WW2 pressing.
