The Peppermint Rainbow was an American sunshine pop group from Baltimore, Maryland, active from 1967 to 1970. They are best known for their 1969 single "Will You Be Staying After Sunday," which showcased their signature style of harmonious, upbeat melodies reminiscent of the vocal group The 5th Dimension. Consisting of two female singers and three male musicians, the group's music was characterized by its layered vocal harmonies and pop orchestration. Despite their relatively short career, The Peppermint Rainbow contributed to the late 1960s pop scene with their light, optimistic sound.
