That's some '60s groove baby
Individually, they are Tommy Boyce and Bobby Hart. Together, they were a singing/songwriting duo who first hit it big in 1964, writing the song "Lazy Elsie Molly" for Chubby Checker. They wrote a string of singles for the Ikettes, Jay and the Americans, Little Anthony and the Imperials, and Paul Revere and the Raiders.
Here's a tidbit for my mother-in-law: they are credited for writing the theme song for the soap opera Days of our Lives!
Don Kirshner brought them on board to produce and perform the pilot episode of the show, writing the theme song and "Last Train to Clarksville". Every original Monkees album (except for the Head soundtrack and 1996's Justus) includes a Boyce and Hart song.
On their own, Boyce and Hart had five hit singles, their biggest being "I Wonder What She's Doing Tonight".
They went on to write for movies and television and made cameos in 70s sitcoms like The Partridge Family as struggling songwriters. According to the Rolling Stone Encyclopedia of Rock & Roll, Boyce and Hart wrote over 300 songs and sold more than 42 million records as a partnership.
The duo worked together and separately throughout the years, notably reuniting and touring in the '80s after the Monkees revival. Hart was nominated for an Oscar for his work on the film Tender Mercies. Boyce taught songwriting in Nashville but struggled with his health and died in 1994.
