Margaret Kerry and I adapted the final scenes for Peter Pan's Magical World of Neverland. We adapted the final scenes from the original ending that was performed only once during the life of J.M Barrie. It was performed on the final night of the initial run of Peter Pan on February 22, 1908 at the Duke of Yorks Theater on the West End in London, England. An Afterthought When Wendy Grew up, is the epilogue to Peter Pan and written, by Barrie, to tell what happened to Wendy when she grew up.
