Hagen). During the first four seasons, the theme song was instrumental only; in the fifth and final season, lyrics (written by Denoff) were added: Diamonds, daisies, snowflakes, That girl. Chestnuts, rainbows, springtime... Is that girl. She's tinsel on a tree... She's everything that every girl should be! Sable, popcorn, white wine, That girl Gingham, bluebirds, Broadway...

In the episode entitled "Señorita," Ann Marie lists her address as 627 East 54th Street.

Ann Marie's acting school was modeled after the Neighborhood Playhouse School of the Theatre on East 54th Street between First and Second Avenues. That Girl was filmed at Desilu-Cahuenga Studios (for many years called Ren-Mar Studios and now called Red Studios Hollywood), located at 846 North Cahuenga Boulevard in
