Might I venture to suggest that Listers should hold their breath for 4' 33" before writing anything further on this subject? What was always an outrage with this piece, I thought, was that John Cage claimed copyright on it when it was "performed". And would a performance of 4' 35" constitute a breach of copyright? Perhaps it would be best put to a useful purpose by its becoming the signature "tune" of Pipedown!? John G. Deacon http://www.ctv.es/USERS/j.deacon http://www.btinternet.com/~pipedown
