COUM continued to operate alongside TG, and in October 1975 they performed "Jusquà la balle crystal" at the Ninth Paris Biennale at the Musée d'art modern. The prestige of being invited to such an event led to the Arts Council awarding them a grant for £1,600, although only the first half of this was ever paid out. COUM's mail art had taken on an increasingly pornographic dimension, and in November 1975 the police charged P-Orridge with distributing obscene material via in the postal system under the 1953 Post Office Act; this trial was set for February 1976.
