Beer Mugs and Boutonnieres

A Vintage Photos Theme Park photo for the theme of: And the band played on (people enjoying themselves while a band plays).

In this real photo postcard, musicians pretend to play an accordion, drum, and triangle in the midst of a group of young men, most of whom have flowers in their boutonnieres and mugs of beer in their hands.

The German sign in the middle appears to say, "Jahrgang. 1895. Die Bassgeig kan̈ein jeder Kratzen selbst der Bär mit seinen Tatzen." But I haven't been able to determine what this means (something about a bass fiddle and a bear scratching himself with his paws?).

In any case, I suspect that these guys enjoyed some more beer and music after they finished posing for the photo.
