This surprising (to me) factoid appears at the end of a 2003 Spectator column about Rolling Stones guitarist Keith Richards:
Richards married for the first and only time on his 40th birthday in 1983, and it probably saved his life. His bride was the 27-year-old Patti Hansen, a home-town girl from Staten Island, New York, and a devout Lutheran. His in-laws gave a startling interview in which they portrayed Keith as an 'enthusiastic disciple of Christ' and that he 'embraced Christ as a way of life'. Under Patti's influence, Richards cut back on drugs, attended church from time to time and even started a gentle exercise regime. 'She's a wonderful girl; I ain't letting the bitch go!' he confirmed in a speech at his wedding reception. Keith may have written 'Sympathy For The Devil' back when, but these days much of his life is spent with a woman who attends a weekly Bible study group and who won't stand for swearing around the house.
Who'd 'a thunk it? I don't know what it means, for sure, but it's interesting.
