Paul & Paula, consisting of Ray Hildebrand and Jill Jackson, were an American pop singing duo famous in the early 1960s. They gained prominence with their signature sound, a blend of light pop and romantic ballads, most notably their hit single "Hey Paula." The song, penned by Hildebrand, topped the Billboard Hot 100 chart, and set a precedent for duets in pop music. The duo's soft harmonies and innocent love-themed songs encapsulated the era's teen pop sensibility, making them a significant part of early 60s pop culture.
