he composed some, here is an example of a Danza and I hear some influences of Gottschalk in some of what he does
Hi visitor

for the sheetmusic, I couldn't compete: The others were so quick!

But I spotted such influences, too, in the nice video! ( Especially: "Souvenirs de La Havane", "Le Mancenillier", and "O ma Charmante,..." could be candidates to compare, I think. )
I found out, that Sanroma has
EITHER a ) arranged this one:
Pers.Main Entry Hindemith, Paul
Title Concerto, piano, arranged.
Imprint Mainz : Schott, 1948.
Descr. 59 p.
Gen. note Arranged for 2 pianos, 4 hands
Top.Subj. - Misc. Concertos (Piano)
Add.Entry Sanroma, Jesus Maria
arranger( e.g. in a Jerusalem library, by which this entry is stated, )
OR b ) Hindemith had DEDICATED the work to Sanroma, which is stated by the 2 versions' entries in the Austrian National library, ( the old one, and a 1974 reprint ).
Then, by struggling through the web as I do often, I found these snippets, too, but it's only info-stuff:

btw, I came across this little page, which might not be
too interesting, I think, if someone should be interested in foreign dances, sheets, etc. What do you think of it?
