The Professor World Band in Bern features Ramblin Dan playing his crazy music machine, also known as The Professor World Band. It was designed as a "Peace Wave Generator" that uses the energy of music to broadcast peace waves throughout the world and works by making people smile and laugh. Ramblin Dan, from New York, traveled the world with his music machine to raise money for children's projects. I encountered them on a sunday-afternoon walk in Bern, Switzerland, while traveling through Europe. See also http://professorworldband.com/
