Kurt Weill - Bert Brecht - Der Jasager (The Yes-Sayer, 1954)

"Der Jasager" (literally "The Yes Sayer" also translated as "The Affirmer or He Said Yes") is an opera (specifically a "Schuloper" or "school-opera") by Kurt Weill to a German libretto by Bertolt Brecht (after Elisabeth Hauptmann's translation from Arthur Waley's English version of the Japanese Nō drama.

Its companion piece is "Der Neinsager" ("He Said No") although Brecht's other text was never set by Weill.
Weill also identifies the piece, following Brecht's development of the experimental form, as a "Lehrstück", or "learning-play".

It was first performed in Berlin by students of the Akademie für Kirchen und Schulmusik at the Zentralinstitut für Erziehung und Unterricht on 23 June 1930 and broadcast simultaneously on the radio. It was successful and there were over 300 performances during the following three years.
Brecht subsequently revised the text twice, the final version, including Der Neinsager, being without music.

Here´s a recording from 1954 with Joseph Protschka as the boy and the "Düsseldorfer Kinderchor" and "Kammerorchester", directed by Siegfried Kohler. Protschka was born in Prague on February 5, 1944. He exhibited talent as a child and thus sang in different performances of "Der Jasager".
