Johns lived in the same building as Rauschenberg with whom he sustained a close personal as well as artistic relationship. They both took part in Kaprow’s ’18 Happenings in 6 Parts.’ Rauschenberg introduced Johns to Cage; they organised a concert of Cage’s music in 1958, because they felt it was neglected. Cage introduced Johns to Cunningham, with whom he collaborated extensively (he also collaborated with Beckett). He corresponded with the aging recluse Hausmann; Huelsenbeck introduced him to Tinguely. He and Rauschenberg met Duchamp frequently from 1960, once celebrating Christmas at a Chinese restaurant.
