I was sad to hear of David's passing. I met him in 1974 when we organized the Associated Audio Archives, and he was an important source for us because of his extensive experiences with sound recordings. I remember one evening after a meeting when David and his wife invited us to his house for dinner. It was, I believe, on that occasion that I first heard of, and heard, the Crepitation Contest. It was an exceptionally enjoyable evening! Garrett Bowles
