Directed by David Schechter, the cast will feature Leslie Kritzer (Sondheim on Sondheim, A Catered Affair, Legally Blonde), Jeff Keller (Phantom of the Opera, Sunday in the Park, Candide), Judy Blazer (LoveMusik, 45 Seconds From Broadway, Titanic), Michael Bartoli (Forbidden Broadway), David Perlman (Yank) and Michael Padgett (Jekyll and Hyde).

Based on a story by Lesléa Newman, A Letter to Harvey Milk has a book by Jerry James, lyrics by Ellen M. Schwartz and music by Laura I. Kramer. The music has been arranged and orchestrated by Ned Paul Ginsburg; Robert R. Blume is a consultant to the authors.

Set in San Francisco in 1986, the new musical is described as such: "What can Harry, a retired kosher butcher and Barbara, a young lesbian writer, possibly have in common? So much more than they imagine! And it all starts to unfold when Harry writes a most unexpected letter, A Letter to Harvey Milk, the martyred gay political leader. Harry's letter sets off a series of life changing events that shake both Barbara's and Harry's worlds. This deeply emotional and surprisingly funny new musical deals with issues of love and loss, truths hidden and revealed, the grip of the past and the miraculous liberations set in motion by the most unexpected people."
