Peter Pan is a musical based on J. M. Barrie's 1904 play Peter Pan and Barrie's own novelization of it, Peter and Wendy. The music is mostly by Mark "Moose" Charlap, with additional music by Jule Styne, and most of the lyrics were written by Carolyn Leigh, with additional lyrics by Betty Comden and Adolph Green. The original 1954 Broadway production, starring Mary Martin as Peter and Cyril Ritchard as Captain Hook, earned Tony Awards for both stars. It was followed by NBC telecasts of it in 1955, 1956, and 1960 with the same stars, plus several rebroadcasts of the 1960 telecast.

The Jolly Roger  Hook revels in his success ("Hook's Waltz"). As the plank is prepared, Hook hears the tick-tock of the crocodile and panics. It is actually Peter with a clock, and while Hook cowers Peter and the Boys help the Indians, the animals and Liza onto the ship and hide. Peter hides in a closet and kills two pirates Hook sends in. A third pirate, Starkey, refuses to obey Hook's order to go in and jumps overboard. The pirates then carry the Boys in, and the Boys pretend to be afraid as they are carried in. Peter disguises himself as a pirate, and the pirates think the "doodle-doo" (named so because Peter still crows after killing the pirates) killed all the Boys. Hook believes the ship is now cursed, and everyone thinks Wendy is the source. The pirates push Wendy to the plank. Peter ditches his disguise and the Indians and animals attack, as well as the Boys who are alive and armed. The pirates are all defeated, and Peter challenges Hook to a duel and defeats him. Hook threatens to blow up the ship with a bomb, but runs into the real crocodile (whom Peter also brought on the ship). Peter catches the dropped bomb and tosses it in the sea after Hook slides down the plank (which is shaped like a slide) with the crocodile chasing behind him. As Peter puts his fingers in his ears, the bomb explodes and Hook is either blown to smithereens or is eaten by the crocodile. Everyone sings Peter's praises ("I've Gotta Crow" [reprise]). Before the Darling children and the Lost Boys go to London, Liza asks Peter to teach her to crow ("I Gotta Crow" [2nd reprise]).  Back home, the Darlings sit by the nursery window night after night, hoping for the return of their children. The children silently reappear and sing to their mother ("Tender Shepherd" [reprise]). The Darlings happily agree to adopt the Lost Boys ("We Will Grow Up"). Wendy promises to wait for Peter, hoping that one day he will return for her.  Years pass, and Peter returns to the nursery, surprising a much older Wendy, who no longer expected him. He has come to take her to Neverland for Spring cleaning, but she declines as she is now grown up; married with a daughter of her own, Jane. Peter starts to cry, and Wendy leaves the room at the sound of her husband's offstage voice. Jane awakes and, like her mother before her, asks, "Boy, why are you crying?" Peter introduces himself, but Jane knows all about him from her mother's stories. She has been waiting for him to come take her to Neverland and to learn to fly. Peter, now happy again, throws fairy dust on her, but as they are about to leave, Wendy tries to stop them, saying, "Oh, if only I could go with you!" In the most poignant moment of the show, Peter answers with a sad but understanding smile, "You can't. You see, Wendy ... you're too grown up". And so Wendy reluctantly lets Jane go, "just for Spring cleaning." Her daughter and the "boy who wouldn't grow up" fly off into the night as Wendy watches from the window.
