During 1967, during the last months of his ten-year "world tour", he visited England, and people there began to join his Spiritual Regeneration Movement. One person who joined was Pattie Boyd, the wife of George Harrison, who was a member of The Beatles. Harrison had learned to play the sitar, an Indian musical instrument, and was interested in Hinduism. He had not found a guru whose teachings interested him. When Pattie told him about the Maharishi, he became interested, and all four Beatles went to a lecture given by the Maharishi. They sent a message to him, asking to meet in person. All of the Beatles were interested in TM, because it was simple and they could continue on as musicians, instead of having to change their lifestyle. They each joined the movement, and began to promote the Maharishi and his teachings. They even announced that they gave up the use of drugs, which had earlier caused for the band, because of what they learned.
