Tommy Boyce & Bobby Hart's "Gonna Buy Me a Dog" played a key role in the episode, and this article highlights an attempt Michael Nesmith made at the song when he produced a backing track for it on July 7, 1966 at RCA Hollywood. That session featured multiple guitarists including Peter Tork, along with Wrecking Crew aces Glen Campbell, James Burton, Al Casey, and Jim Helms. The bassist was Bill Pitman, while Hal Blaine played drums and Billy Preston handled organ duties.
Nesmith's backing track never received a vocal and went unheard until 2006 when it was released on a deluxe edition of The Monkees' debut album. Boyce & Hart later cut their own (drastically different) version, and it was this take that was ultimately included on The Monkees.
