These performances are only a very small fraction of the activist group’s work. Most of their energy is consumed by more conventional protest, and their agenda is expansive but consistent. Their first major area of concern, when they formed around 2005, was the western world’s rampant consumerism – hence ‘stop shopping’. They’ve protested – and occasionally been arrested – at Times square, Main Street outside Disneyland, Starbucks and the Occupy Wall Street movement. Reverend Billy ran for mayor of New York in 2009 on the Green party ticket. Although they’re based in New York, Billy and his Choir have visited England as well as many parts of the the States.
