Directed by Signature artistic director Eric Schaeffer (Follies, Million Dollar Quartet), the musical — chronicling a decades-long friendship between two women — stars Davi (A Chorus Line, The Drowsy Chaperone) as Bertie and Umphress (American Idiot, On a Clear Day You Can See Forever) as Cee Cee Bloom.

Beaches, originally scheduled through March 23, was given a week-long extension through March 30. Opening night is set for March 4.

Based on the 1985 novel by Dart (later adapted into the 1988 movie with Midler and Hershey), the musical features a book by Dart and Thom Thomas, lyrics by Dart and music by David Austin.

Beaches, according to Signature, "follows two extraordinary friends through 30 years of camaraderie, laughter and sorrow. Vivacious, outlandish Cee Cee and beautiful, privileged Bertie meet as children and become fast friends. From pen-pals to roommates to romantic rivals, Cee Cee and Bertie's oil-and-water friendship perseveres through even the most tragic trials. With a touching vulnerability, Beaches exemplifies the triumph of the human spirit and the bonds of sisterhood."
