My hubby and I went to a comedy-concert of "Der Popolski- Familie" yesterday. They are a group of fantastic musicians pretending they are a family from Poland with a granddad who was the composer of every famous pop song (as Polka) worldwide.

And all of them were speaking German with a false Polish accent ...
They all are playing different characters: one is the introvert shy bassist, another is the sexy female singer cousin searching for a wealthy husband, two are twins playing wind instruments and wearing checked jackets, one is the extrovert drummer and so on ... they all are a bit crazy, lunatic

telling their stories with brilliant music.
The audience was asked to dance and sing in between - we all had big fun and my hubby who is very critical with musicians at times was very content and happy with them!
Just a tip for Germans and People from nearby, but worth every Euro
Here is a bit of a TV show with them
