The actor and playwright appeared alongside late funnyman Williams in the 1993 movie and in January (15), Oscar-winning composer Alan Menken revealed he and his Hercules collaborator David Zippel had been hired to write the songs for the stage production.

However, according to the New York Post, Zippel has since been fired from the project after it became clear the songs didn't work during a reading of the show, which is still in development.

A source tells the publication Fierstein and Menken remain onboard the production, stating, "This really is a passion project for Harvey."

A replacement lyricist has yet to be announced.

Mrs. Doubtfire starred Williams as divorced dad Daniel Hillard, who cross-dresses as a nanny so he can see his kids. The tragic comedian had been planning to reprise his role for a sequel before committing suicide last summer (14).
