BILLY DAVIS, JR. is 80 today. After many years as a member of the Fifth Dimension, he and his lovely bride Marilyn McCoo went solo and scored a few hits on their own, including the #1 classic "You Don't Have to Be a Star." Their romance is documented in the #1 hit "Wedding Bell Blues (Won't You Marry Me, Bill?)." An oddity in Hollywood - Billy & Marilyn are still together today.
