It seems a Broadway adapation of the Disneyland Aladdin musical is still being working on. In an interview with Ultimate Disney Alan Menken stated.
Menken: The main things that are going on is Leap of Faith is opening here at the Ahmanson Theatre on October 3rd. Thatâ€™s my gospel musical. Sister Act is running in London at the Palladium, and coming to Broadway in the spring. So those are my two, big, active projects, and then there is a stage musical of Newsies, Hunchback, and Aladdin all coming.
