I was able to identify the middle portion of the video as being from the song "Muss i denn" but I'm interested in finding out what the portion before that is (when the flagbearers and lancers are coming out).

It's almost certainly some military march accompanied by vocals (especially given it's at a military tattoo) but I can't make out the lyrics they are singing.

Any help would be appreciated, thank you!
