Five-time Grammy-nominated performer and songwriter Michael Feinstein is known for performing the works of others from the great American songbook. But now he is working on adding to it with The Gold Room, a two-person musical based on the life of Woolworth heiress Barbara Hutton, which will get an April workshop in London with Melissa Errico singing the lead.

The industry-only workshop is not open to the public.

Composer Feinstein has been collaborating with lyricist-librettist Warner Brown (Walking With Dinosaurs ) on the project since at least 2009.

Errico has starred in six Broadway shows (My Fair Lady, Amour, Irving Berlin’s White Christmas, High Society, Dracula, the Musical and Anna Karenina). She will be joined by London’s Jamie Muscato (Bend It Like Beckham, Dogfight and Les Misérables).

Tony Award-nominated director Jeremy Sams (Noises Off, The Sound of Music) will helm the workshop. According to production notes, “The score is contemporary and sophisticated, exploring the fragile psychological state of ‘the richest woman in the world.”

Feinstein has performed numerous concerts throughout the world and on Broadway. His albums include The Sinatra Project, Michael and George: Feinstein Sings Gershwin, Hopeless Romantics, Big City Rhythms and Romance On Film, Romance On Broadway. He is co-owner of his namesake Feinstein's/54 Below club in Manhattan, where Errico is scheduled to perform April 1 and 2.

Tony Award winner Victoria Clark (The Light in the Piazza) and Tony nominee Jonathan Groff (Spring Awakening, Hamilton) took part in a 2010 Manhattan reading of the tuner.

The Gold Room is currently under option to London producers United Theatrical and Covent Garden Productions.
