No somos de piedra Soundtrack (1968) OST

Lucas, typical average Spaniard, shy, gray and repressed, is married to sanctimonious Enriqueta, so he is always aware of other women, although the couple are already parents of nine children, which is why Lucas will do the unspeakable to convince his wife to take the contraceptive pill, something practically sinful for a practicing Catholic like Enriqueta.
