The Peppermint Rainbow was an American sunshine pop band from Baltimore, Maryland, active from 1967 to 1970. Their musical style was characterized by harmonic, upbeat tunes reminiscent of the late 1960s pop scene, greatly influenced by acts like The 5th Dimension. They are best known for their hit single "Will You Be Staying After Sunday," which reached number 32 on the Billboard Hot 100 in 1969. Despite their brief tenure, The Peppermint Rainbow made a notable impact on the bubblegum pop genre.
