Trying to figure out this Marching Band Song

Clint1

It's in the movie Frogs 1972 on YT at the 38:04 mark. Didn't say anthing in the end credits. Can't post the link to the video. Been listening to all the marching band songs on YT to no avail. Can't find this song to save my life.

It sounds like it might be a marchified version of "The Yellow Rose of Texas"?

Calica

It's not Yellow Rose of Texas, but it definitely sounds like something from that era - possibly a medley; there are at least three distinctly different sections.

Try looking for Confederate fife and drum tunes from the American Civil War.

This is a tough one.

Elvenshae

It's almost certainly a Dixie variation, but it sounds like it's shading into, like, Yankee Doodle Dixie:
