From 18 to 23 January, Hans Holzbecher was in Hamburg for a remarkable radio recording. "Kuno Knallfrosch" is not only a little frog with a big bang, but also a wonderful children''s book with marvellous music by Dietmar Jacobs and Andreas Schnermann, bathed in image and colour by Horst Klein. Together with the incredible NDR Bigband under the direction of Ralf Hesse, Hans Holzbecher took to the stage of the Rolf Liebermann Saal at the live recording, before a total of 3,000 delighted children, and told the story of the little frog and his friends.
