It would seem that what had been going on was something of a war, with buskers competing for pitch using the amplification of their systems as a main weapon against the competition. It had been going on for some time, and the buskers had refused to cooperate, so this was simply the final straw of a problem the Cathedral had tried to live with for three years. As the offenders were playing just a few Simon and Garfunkel songs, they are now reduced to The Sound of Silence.

Mind you, if anyone tries interfering with my equipment when I'm singing in the bath, they'd better be prepared for a 4" loofah where the sun don't shine.
