I'm sorry, I intended to link a video to my post but it didn't work.
The sheet says "Tambour Major" under magnification, but a friend says
it is not from the Offenbach operetta.

A mistake would not surprise me -- #5 on the tune sheet reads "Cloches
de Corneville" but the tune is Verdi's "Vivra, contende il giubilo".

Here is another try for the video: https://youtu.be/4SvfYWsLxe8
 

The first tune I can't identify, the second tune is the Verdi, the
third is Sweet Heart, by Arthur Sullivan
