I guess I'll add my opinion to the fray.
The words to the phrasing at the end of the "Closing Credits" track on the Glory soundtrack are:
Blow the horn, play the fife, beat the drum so slowly
Blow the horn, play the fife, make the drum beat . . . lowly"
I think that "lowly" is the final word because I believe I have heard that refrain before (in another movie many many years ago) and I'm pretty certain that "lowly" was a part of it...
Only...glory...nobly. Hmmmmm...I guess it doesn't make any difference. This is by far my fav James Horner soundtrack (leave it on my Ipod all the time).
