Boyce & Hart, the songwriting and (later) performing team of Tommy Boyce and Bobby Hart, are most famous for writing several of the Monkees' big hits, including "Last Train to Clarksville," "Valleri," and "(I'm Not Your) Stepping Stone." Together and separately, they also wrote or contributed to hits by several other acts in the 1960s, including Freddy Cannon, Curtis Lee, Little Anthony & the Imperials, and Jay & the Americans. In 1967 they began recording on their own as a duo, landing a Top Ten hit the same year with "I Wonder What She's Doing Tonite." Based in Los Angeles, Boyce & Hart were a West Coast equivalent to the kind of craftsmanship and methodology espoused by Brill Building songwriting teams, although their material was less meaningful and enduring than Goffin-King's or Barry-Greenwich's. They emphasized bright, happy, AM radio melodies with room for lots of vocal harmonies, an appropriate vibe for the Monkees and other acts; it was typical of the L.A. late-'60s pop/rock that would retroactively be dubbed "sunshine pop."
