Lolita, My Love.
From The Lost Media Wiki
There is a Philadelphia recording of the show, although it is low quality. There are also several demo's made of the show. Some sung by session singers, some by Lerner himself to a crowd of producers. There is also a Boston tryout script available, as well as some sheet music. "In The Broken Promise Land of Fifteen" and "Lolita" both sung by Humbert Humbert are available for purchase online.
