The Cast Showoff: In the original production, "Another Hundred People" was written specifically for Pamela Myers for the role of Marta, a lengthy song for a relatively minor character. The dance sequence "Tick-Tock" was created by choreographer Michael Bennett for his future wife Donna McKechnie, the original Kathy; the number is frequently cut or abridged in subsequent productions. In the recent Lincoln Center production, Neil Patrick Harris performs a few magic tricks during one of the musical numbers.
Cut Song: "Happily Ever After", "Marry Me A Little" and "Multitude Of Amys", although "Marry Me A Little" was later put back into the show as the act I finale. "Tick-Tock" is also frequently left out of productions, although it was included in the 2011 concert staging, as well as the 2018 revival.
Follow the Leader: The sound of the show was heavily influenced by Promises, Promises, the Burt Bacharach musical from the previous season. Jonathan Tunick, the orchestrator of Promises, Promises, was hired to orchestrate Company in the same style, including a group of wordless singers (referred to in the program as "The Vocal Minority").
The Other Marty: The show initially starred Dean Jones in the role of Bobby Baby, and he even recorded the role on the cast album. However, right after opening night, Jones departed due to suffering a nervous breakdown from his divorce. He was replaced by Larry Kert, best known for originating the role of Tony in West Side Story. As a result, Kert was nominated for a Tony, making it a rare case for a replacement receiving a nomination.

"Being Alive" for Raúl Esparza, who reportedly got a five-minute-long standing ovation upon finishing the number on opening night of the 2006 revival. Subsequent performances weren't much less impressive.
Sondheim had never been in love, let alone been married when he was writing Company. So for research, he reached out to his good friend Mary Rodgers (daughter of Richard Rodgers and inspiration for Mary Flynn in Merrily We Roll Along) who was on her second marriage. They spent an evening together, and Sondheim interviewed her about what she felt marriage was all about. The result was a show critics and audiences consider to be one of the most insightful looks into the nature of love, marriage, and relationships.
