Are animals turned on by the same things humans are? The Trentham Monkey Forest in Stafford, England, hired a Marvin Gaye impersonator to sing “Let’s Get It On” and “Sexual Healing” (among other songs) inside their Barbary macaque habitat. Park Director Matt Lovatt says, “We thought it could be a creative way to encourage our females to show a little affection to males that might not have been so lucky in love. Females in season mate with several males so paternity among our furry residents is never known. Each birth is vital to the species with Barbary macaques being classed as endangered.” He added that zookeepers expect to find out if the visit had any effect on the monkeys when the birthing season arrives in late spring or early summer.
