Gesangskollektiv Michael Ritter

In the page's words:

The singing collective Michael Ritter are Hannes, Max + Friends. We have been organizing sing-along parties on a very small and sometimes larger scale since 2013! Kind of karaoke, but somehow not. Because lyrics aren't just for the stage - they're for everyone.

We also love light, decoration and the odd gimmick.
The benefit of the event is the fun!
