The popular pianist and composer Dave Brubeck is still touring the world at the age of 73. In the first of an eight-part conversation with Geoffrey Smith, he recalls his upbringing on a ranch in California in the 20s, with a cowboy father and a pianist mother. "My dad would not go to a symphony concert, saying it hurt his feet to walk on cement." Early influences were Fats Waller, Stan Kenton and Art Tatum. Producer Derek Drescher
