Can it be? Yet another song that hit #1 that has slipped into the Forgotten Oldie category? Yup! The Partridge Family released "I Think I Love You' to coincide with their new TV show in 1970, and the song exploded to number one in the USA, Canada, Australia and New Zealand. Sung by show stars David Cassidy and Shirley Jones, the song has almost disappeared from the airwaves.
