Aviation Rag (written under an assumed name because he was a teacher and Ragtime was scandalous at that time)

http://www.rtpress.com/mid/kel/liont_sk.mid There's another piece, a light classical selection called "Abendlauten" Evening Chimes. I couldn't find a Midi file. Professor Bill had it on his site, but the page is dead. The sheet music is out there.
He was a publisher, musician, teacher, and orchestra conductor. His music is known all over the world and some mystery surrounds songs that have his trademark harmonies, but were penned under other names. My theory was either he didn't want to be known as a Ragtime composer, or he published under several names to give the appearance that his publishing house had several clients.
If you are in the old part of New Albany Indiana, you can see his family name in paving bricks on some sidewalks. Some relative must have owned a kiln nearby. That's a mystery that needs to be solved.
