A more or less coherent assemblage of truants, malcontents and other assorted Frenchmen, the Master Musicians of Dyffryn Moor agreed to be manacled to a rock named rhythm in the name of charity and/or community service. This was in a time when neo-cons and rapists freely roamed the land, and when the unwritten law was that water should be drunk only out of "glasses".
