I want to get a cross reference about a figure of speech which is common in the Berlin-based part of my family. They use very commonly the phrase "bis Motzen tutet" to emphasis the circumstance that something takes long or takes part at a very late hour.
My aunt explained to me this goes back to some "tower musician" (Turmbläser) in the olden Berlin that played his instrument to call out the beginning of the night. He was, according to her story, named Motzen. Can anyone confirm her story and direct me to more information about this legend?
The internet (read: google) did not present anything about it to me. I don't know where else I could start my online-search for legends like this.
