According to the Internet source given below, the mixed choir Chor Courage,Berne was founded in 1997 on the initiative of Karin Logemann and Dirk Ibbeken initially with 18 members.
Today (writing in July, 2019), they comprise 38 men and women aged between 27 and 75, who rehearse weekly.

Through the good office of Monika Jenne who I knew as a member of De Saitenspeeler I was invited to join Chor Courage to join their project to sing Wolfgang A. Mozart's Krönungsmesse KV 317 in 2001. For almost a year I would make a weekly pilgrimage from Bremen-Vegesack to Berne for rehearsals. After having sung for 3 years with the very formal Collegium Musicum Bremen it was quite an experience singing such a work in such a setting. Having known rural choirs such as the Männerchor Meyenburg and their idiosyncrasies, it was no great surprise that the basses very quietly and surreptitiously passed bottles of beer amongst themselves whilst the leader, Dirk Ibbeken, was occupied by the other voices. Happy memories indeed!.
The concert was finally given in the St. Aegidus Kirche in Berne in 2002.
After I left the choir, I was presented with a handsome signed photograph of them which still adorns my "music room". At my retirement "concert" (Ceilidh 2003) the Courage Chor rejoined me on the stage of Gustav-Heinemann Bürgerhaus.
