Batt had used Cage's name for "obvious reasons," Caprioglio said to evoke Cage's provocative 1952 composition. "If Mr. Batt wants to produce a minute of silence under his own name," he conceded, "we would obviously have no right to the royalties."
So in a sense, Batt's defence comes down to "I credited John Cage as a joke, but shouldn't be expected to pay real royalties, because 4'33" is not a real composition"; which sounds a bit too much like the "modern art is rubbish" argument. (via the Horn)
