Hornist Klaus Wallendorf had a special birthday surprise during a rehearsal in Beijing. As expected, the Berliner Philharmoniker and conductor Gustavo Dudamel began with Gustav Mahlers Fifth Symphony, which suddenly turned into a sonorous Happy Birthday, arranged especially for the occasion by Joshua Davis.
