Included in this file are two versions of a piece of music by Marshall: the original, and Proulx's edition. In Proulx's edition, he simply respelled Marshall's original parts for 3 trumpets and 3 trombones into parts for 4 horns in F, added a flute part, and slightly changed the string bass part. I'm guessing that he did this so his own musicians could play it. It is unclear if Proulx's version was ever published.
