“One Man Shy” (a.k.a. "Peter And The Debutante") (prod. #4722) first aired @ 7:30 p.m. (EST) on NBC as the 13th episode of The Monkees.

Kellogg's originally sponsored this episode, which featured the songs "You May Just Be The One," written & produced by Michael Nesmith, and "I'm A Believer", written by Neil Diamond and produced by Jeff Barry, a phenomenal tune which made its debut appearance in this episode. Released as the A-side of the Colgems #66-1002 single on November 12, 1966, the song was heavily hyped by NBC, as it was used in every episode of The Monkees TV series aired on The Peacock Network in December 1966. All this, naturally, resulted in "I'm A Believer" being The Monkees' biggest hit (a 7-week stay at the top of the Billboard chart!), not to mention the Top song of 1967! "I'm A Believer" made no further appearances on The Monkees TV series beyond December 1966 (save for a brief snippet in the final minutes of Episode No. 32, “The Monkees On Tour”, the show's first season finale), but Micky can be heard briefly mentioning its title in Episode No. 38, "I Was A 99-lb. Weakling" (a.k.a. "Physical Culture"), and he also performed "I'm A Believer" in a duet with Julie Driscoll in the 1969 NBC-TV special 33⅓ Revolutions Per Monkee.
