Tommy was best known as one of the writers, along with Bobby Hart, of the Monkees first album and TV show including both "(Theme from) The Monkees" and "Last Train to Clarksville."

In the mid-1970s, Boyce and Hart reunited with Davy Jones and Micky Dolenz, performing the songs Boyce and Hart had written for The Monkees a decade before. Legally prohibited from using the Monkees name, they called themselves Dolenz, Jones, Boyce & Hart.

Tommy struggled with depression, and on November 23rd 1994, he committed suicide at this location.
