Polly Stone sings the alphabet for Grover

Polly Stone (b. November 1966) is the daughter of Sesame Street writer/director Jon Stone and actor Beverley Owen.

Polly appeared in at least two segments on Sesame Street: one in which she recites the alphabet with Grover, and another where she demonstrated five fingers. Decades later, she's still recognized for appearing on the show, having been identified by a pre-schooler as she recounted in Sesame Street: A Celebration - 40 Years of Life on the Street. She also appears in Episode 0212, Episode 0384, and Episode 0393 during the Sorting Songs segments.

In his 2008 book Street Gang: The Complete History of Sesame Street, Michael Davis describes her as someone who, as a child, would have her handprints all over Sesame Street, and that she and her sister Kate were "Sesame Street’s in-house, on-demand focus group" who contributed countless ideas for script material on the show. One notable example is Christmas Eve on Sesame Street, directed and co-written by their dad. Polly recounts that the plot came from her and her sister wondering how Santa Claus got down the chimney to deliver presents. The end product is a special that Dulcy Singer called "Jon's baby from the beginning. If you want to see his soul, watch Christmas Eve on Sesame Street."

Years later, Polly assisted her father and Joseph A. Bailey in location scouting for the unproduced special Big Bird in Ireland. She later became a school teacher and interior designer. Both sisters are interviewed in the 2021 documentary Street Gang: How We Got to Sesame Street.
