The musician John Lennon and his wife, Yoko Ono, went through primal therapy in 1970. A copy of the just-released "The Primal Scream" arrived in the mail at Lennon's home, Tittenhurst Park (sources differ about who sent the book). Lennon was impressed, and he requested primal therapy to be started at Tittenhurst. Arthur Janov and his first wife, Vivian Janov, went to Tittenhurst in March 1970 to start the therapy, which continued in April in Los Angeles. Arthur Janov went to Tittenhurst after giving instructions in advance about the isolation period and giving instructions to Lennon to be separated from Ono. Lennon and Ono had three weeks of intensive treatment in England before Janov returned to Los Angeles, where they had four months of therapy.
