"While on tour in 1971, Spencer told his bandmates that he was going to the store to buy a magazine. He never returned. After several days of searching, the members of Fleetwood Mac learned that Spencer had purportedly decided to join a religious group called the Children of God, which has faced criticism for being a cult. He had allegedly been spending some time with the group, and claimed that a feeling of disillusionment caused him to leave the band to join the Children of God. "Bottom line, I had to leave in order to step back from the picture and get my life sorted out," Spencer said. "I wouldn’t be here today if I hadn’t and they would not have gone on to be one of the biggest bands in history!""
