Great link, Phil.

Now, M Gideon seems to have been an American who came over here, acc to wikipedia entry ~~

-"Melville Gideon (May 21, 1884, New York City – November 11, 1933, London) was an American composer, lyricist and performer of ragtime music, composing many themes for hit Broadway musicals including The Co-Optimists. He was also a director, producer and performer"-

... tho that 'including The Co-Optimists' seems a bit confusing, as it wasn't a Broadway musical'. In fact it's a slightly confusing entry, appearing in the first clause to suggest that he only composed & performed ragtime, but then implying much wider musical interests and accomplishments.

Still, all these various links & contributions, taken together, do seem to settle the question of origin & composition, which is what I was after.

Very many thanks to all.
