After George Harrison and Pattie Boyd divorced, they maintained a more friendly relationship than the one they had while married. The same could not always be said about Boyd’s relationship with her second husband, Eric Clapton. Boyd, Harrison, and Clapton were all at the same party, and Clapton behaved coldly toward her. She explained that she and Harrison laughed at his behavior. Harrison and Boyd married in 1966. Their marriage was happy at first, but when he began dedicating himself to spiritualism, she felt alienated from him. They grew further and further apart, something that wasn’t helped by infidelity on both sides. On New Year’s Eve in 1973, Harrison told Boyd he wanted a divorce at a party.
