Dempsey, an uileann piper, was invited to play for Hitler and propaganda chief Joseph Goebbels during a visit to Berlin in 1936 after being told that Hitler was an Irish folk music fan.
When he arrived to play however, there was no room for him to sit, which he needed to do to play, and it looked like it would be canceled.
however, Hitler jumped up and demanded that an S.S. member get down on his hands and knees and that Dempsey sit astride him while he played.
Dempsey played what was described as a ‘haunting air’ as Hitler listened with rapt attention. After he performed, Hitler presented him with a gold fountain pen while Goebbels clapped wildly.
