Silent disco

'When disco nights roll around this summer at the Glastonbury Festival in England, neighbors may well wonder if they have lost their hearing. If all goes as planned, they will have little cause for their usual complaints of noise. Plans call for a "silent" disco, where the dancers will be equipped with headphones through which the music will be piped. "There are about a thousand residents within two miles of the festival location, and it's important to keep noise down, but first and foremost, it's a fun thing to do - the first time its been tried in the U.K.," explained Emily Eavis, co-organizer of the festival.'
