My arrangement is available with brass (and timpani) accompaniment. It is scored for USA-type brass, so trombones are in bass clef, horns in F, etc.

The middle movement especially is changed from the standard solo-band versions of this piece. A good band and conductor might be able to work with the old Mantia version of the accompaniment. One of the reasons I chose to re-score for just brass was to avoid the old-style woodwind writing of the Mantia-Brasch version, which was not especially attractive to the sounds woodwinds can produce (but... shhhhh about that - it's a secret!).
The link above has an MP3 file, which will let you hear what the brass version sounds like.
