The title change from of "Muskrat Scramble" to "Muskat Scramble" makes sense when one considers that British labels, in particular, usually listed the same Kid Ory song as "Muskat Ramble" rather than the correct "Muskrat Ramble".
Strange that the British typesetters couldn't get it right. The additional images that jago125 added of his copy show that the correct title had even been scratched into the wax.
Added images of a 1950's pressing.
Also two more showing writing in the original wax; detail of matrix no. and larger view of Muskrat Ramble, sic.
The other side is likewise adorned and both sides have "S.C." at the bottom.
Both tracks were recorded in Chicago on August 13, 1929.
A side matrix, C4035A. Other: 4968.
B side matrix, C4036A Other: 4968-
Moderator: my apologies, the additional pictures are of course the B side and I've written 'A' on the pics., which is incorrect.
Also, release date is 1931. Not as shown on the original contribution. [Thanks, now fixed! Mod.]
