I very much enjoy playing a swing etude called "Etude 2" for tuba. (See attached image of first two measures, which I trust does not breach any copyright.)
I would very much like to know who wrote it, and where to get hold of a copy. I would also very much like to get hold of a copy of "Etude 1" by the same composer.

Can anyone in the TubeNet community help me solve this riddle?

Not the same but they may also float your boat?

Thanks very much. I already have those two, which I found while searching for the elusive one above.
