This single is a Chilean rarity. Hard to find. On the A side, Bee Gees plays "Corre Hacia Me" and "Mi Mundo", on the B-side David Cassidy plays "Cherich" and "Come Puedo Estar Seguro". Unfortunately, the condition of this single can be described as "heavily used". Still, a nice piece for a small collection of rarities.
