Rev. 2a (2019) - full version (2:55m), for experienced
players. This version is released because several horn
players have written of their ability to reach a
high-D.
Rev. 2b (2019) - is the shorter original-length version
(1:40m, with slight modifications to version 1b) but
without the higher notes of version 2b. Perhaps
suitable as an encore or opener.
