They'll be spreading the word of Earthelujah and encouraging us all to join the struggle to avert the threatened Shopacolypse. Expect humour, great music and an unshakeable belief.
The Church of Stop Shopping is a New York based secular political religion founded in 1999.
Their performances in concert halls (and the Tesco cash tills exorcisms) are directed by Savitri D, who co-founded the "church" with Talen in the months after 9/11.
Since Trump, the Frankenstein of shopping culture, won - or stole - the election, the church has been a repository of community anguish.
The choir has opened for Neil Young, been produced by Laurie Anderson, and hosted a Black Lives Matter benefit with Joan Baez as well as hosting their own parades, boycotts, and protests – all whilst singing multiple harmonies.
To date they have performed in, and Billy has exorcised cash registers in, over a dozen countries and four continents.
The Rev has an advice column in a New York newspaper called "Trump Depression Hotline" – and this effort to bring mindfulness and hilarity to these dark times became the name of the UK tour.
"We gotta love everybody and show them we care 'til they can't Trump anymore" he said.
Savitri D and Reverend Billy have taken to spending time in the public garden of Trump Tower:
"We walk past the submachine guns and dogs, the body armour and the golden name of the white supremacist president that hovers in space above the door" said Rev Billy.
"We travel up gold-plated escalators to legally protected privately owned public space then we write together for 45 minutes. At the end we stand with our writing and recite or shout or sing our words at the 700 foot tall gold-tinted monstrosity" added Savitri D.
Reverend Billy & the Stop Shopping Choir at Marlborough Theatre, Brighton, on Tuesday 24th October 7.30pm. CLICK HERE for more info.
