In 1966, Hart and Boyce were tapped to write songs for the Monkees television series, and with such an immediate demand for a large quantity of material, the duo managed to place quite a few compositions with the group (they were even originally considered for membership). Their Last Train to Clarksville became the Monkees' first hit, going all the way to number one later in 1966. In addition to the show's classic theme song, Boyce Hart songs in the Monkees' repertoire included I Wanna Be Free, She, (I'm Not Your) Steppin' Stone, Words (these latter two both hits the second time around), and Valleri. Boyce Hart also produced most of the group's early work, and sometimes played or sang backup on the recordings. With the Monkees demanding more control over their music, Boyce Hart explored a recording career of their own, in much the same vein as their work with the Monkees -- sweet, hooky bubblegum pop. In 1968, they scored a Top Ten hit with I Wonder What She's Doing Tonite, but their recording partnership proved short-lived. They returned to production work for the Monkees over 1969-1970, then went their separate ways.
Hart composed music for the 1972 film #Unholy Rollers, but with bubblegum pop on the way out, he was largely inactive in the musical arena. In 1975, he and Boyce reunited with their supporters in the Monkees, Micky Dolenz and Davy Jones, for an international tour as Dolenz, Jones, Boyce Hart (billed as "The Guys Who Sang 'Em and the Guys Who Wrote 'Em"). The foursome recorded an album for Capitol in 1976, but broke up the following year. Boyce Hart reteamed for a while to work on music for the cartoon shows #Scooby-Doo, Where Are You? and #Josie and the Pussycats; meanwhile, the Sex Pistols turned (I'm Not Your) Steppin' Stone into an unlikely punk anthem. Separated from Boyce again, Hart worked on the soundtrack of the 1983 film #Tender Mercies, earning a Best Song Oscar nomination for Over You (co-written with Austin Roberts). He subsequently worked as a producer and/or writer with New Edition, LaToya Jackson, and Robbie Nevil, among others. ~ Steve Huey, Rovi
