A friend with a taste for newspaper archives and curiosities sends this link: a Catholic Herald story from 1967 titled Bunnies’ Sunday survey . An interdenominational magazine called Sunday surveyed the “bunnies” from the London Playboy club and found:
Nearly half the girls are C. of E. [Church of England, i.e., Anglican], a third Catholic, including a convert, several are Baptists and one is a Spiritualist. Half the girls never go to church, except for the occasional wedding, the Baptists go infrequently, one Anglican goes every six to eight weeks and the Catholics go every Sunday when they are not working.
They all said they prayed, but when asked if they’d prayed to become a bunny, “they all replied with a resounding ‘No’.”
