a few years ago during a concert of the great Brandon Power (blues harp) and Michael Lempelius (Bouzouki/Mandolin) I heard Michael singing a song (because just in that moment Brandon wanted to start his song he had a nosebleed). So Michael used the moment to sing a song in German (because he is German and the concert was in Germany and so everybody except Brandon understands everything of the song). It was a brilliant version of the song "Billy Taylor".
The name of Michael's Song was "Willy Dose" with the same tune but German text. Now, I am looking for this German version.
Thanks everybody out there
Greeting from Germany
