From an early age it seemed that Weldon took a keen interest in music. His natural musical abilities were quite evident even while in elementary school where he certainly stood out amongst his classmates. In 1973, his mother took him to audition for the Honolulu Boy Choir where his singing talents were quickly recognized by director Roy Hallman. As a member of the choir, Weldon participated in performances through out Hawai‘i and extensively toured the continental US, Mexico and Canada.
