Weird sexual relationships in those hippy trippy days (maaaannn)
In 1966 George married Patti Boyd, a noted model.
In 1973, exasperated with him (various reasons) she had an affair with Ronnie Wood (The Faces and the Stones) then left George in '74 due to numerous infidelities of his own.
One of which was with Ringo's wife, Maureen.
In 1979 Patti then married Eric Clapton, George's friend (whom he remained friends with throughout!)
Patti divorced Clapton in 1989 due to his numerous infidelities... and his domestic abuse.
Free love, maaan.
