The disc will be recorded Jan. 5, 2004, for release March 9, Fordin said, though the producers have not announced a recording plan and a spokesman for the show said no deal has been signed.
Murphy plays the tough talking older sister, Ruth, in the show based on the comedy, "My Sister Eileen."
The orchestra, conducted by Rob Fisher, will be sweetened with six additional strings, reflecting the sound heard in the Encores! concert that inspired the full stage revival.
A number of albums of the score exist (including Broadway and TV cast albums, both starring Rosalind Russell), but Fordin said the reasons for doing this new one are clear: The production's energy and Murphy's incandescent performance.
