Myself, I've always preferred _The Bonnie Blue Flag_, but they didn't ask my opinion.;-)Likewise. And this leads to a minor flub that I spotted in 'Glory.' A Union band playing _The Bonnie Blue Flag?!?_
Might not be a flub. 'The Bonnie Blue Flag' tune was used for a few Yankee songs also. I know the 69th NY Irish used the tune for the song 'Irish Volunteer'. It is pretty much the same as the tune for British songs were the same as some Rev. War American songs.
