We were invited to contribute to Will Holder's Bachelor Party, a celebration of Marcel Duchamp's 121st birthday held as part of Nought to Sixty at the ICA, London.

As the evening's programme of events drew to a close, the ushers interrupted proceedings and invited everyone to leave the building and congregate outside, ushering out drinkers in the bar and loiterers in the foyer. Once the building had been emptied and everyone gathered together we took their picture and then allowed them to return.
