The $ounds of $ilence LONDON -- There's a copyright infringement case in the works -- involving silence. British composer Mike Batt's newest CD, "Classical Graffiti," includes the composition "A Minute's Silence." It's a minute of -- you guessed it -- silence. As a salute to avant-garde composer John Cage -- who in 1952 composed "4' 33" " (yup, 4 1/2 minutes of silence) -- Batt credited his track to "Batt/Cage." Now, Cage's publisher wants its percentage of the royalties. "When the record company registered the track with the MCPS it was credited to Mike Batt and John Cage, so royalties would have been due to John Cage," a spokesman for the publisher told BBC News Online. Batt told the BBC his silence is an original work. "I certainly wasn't quoting his silence. I claim my silence is original silence," he said. Both tracks were performed in court, the BBC reported.
