On the Beatles' return to England, rumours began to circulate that they had decided to break up. George Harrison informed Epstein that he was leaving the band, but was persuaded to stay on the assurance that there would be no more tours. The group took a three-month break, during which they focused on individual interests. Harrison travelled to India for six weeks to study the sitar under the instruction of Ravi Shankar and develop his interest in Hindu philosophy. Having been the last of the Beatles to concede that their live performances had become futile, Paul McCartney collaborated with Beatles producer George Martin on the soundtrack for the film "The Family Way" and holidayed in Kenya with Mal Evans, one of the Beatles' tour managers. Lennon acted in the film "How I Won the War" and attended art showings, such as one at the Indica Gallery where he met his future wife Yoko Ono. Ringo Starr used the break to spend time with his wife Maureen and son Zak.
