Andrea Marcovicci and Susan Watson are headliners in the seventh annual 42nd Street Moon series of musicals in concert in San Francisco March 1999-January 2000.

Marcovicci, known for her cabaret work, will play Daisy Gamble in the concert version of Alan Jay Lerner and Burton Lane's On a Clear Day You Can See Forever in September 1999. Onetime ingenue Watson, remembered for playing the original Kim in Broadway's Bye Bye Birdie, will sing the role of Dolly Talbo in the Truman Capote-inspired The Grass Harp in November 1999.

The season opens March 10-April 4, 1999 with the Jerry Bock and Sheldon Harnick's Pulitzer Prize-winning Fiorello! and continues with Jerome Kern's Sitting Pretty (Aug. 4-22), On a Clear Day... (Sept. 8-12), Cole Porter's Let's Face It (Sept. 29-Oct. 17), The Grass Harp (Oct. 27-Nov. 14) and Rodgers and Hart's Babes in Arms (Nov. 24, 1999-Jan. 2, 2000).

All performances except On a Clear Day... are at the 130-seat New Conservatory Theatre, 25 Van Ness Ave. (at Market) in San Francisco. A larger venue is being sought for the star-driven Lerner-Burton tuner, which is expected to be more popular due to Marcovicci's casting.

The Grass Harp was a 1971 Broadway vehicle for Barbara Cook, but was a quick flop. The score was by composer Claibe Richardson and lyricist-librettist Kenward Elmslie, based on the novella by Capote. 42nd Street Moon is one of several professional musical theatre concert series, including the Barbican Theatre's "Discover the Lost Musicals" in London and York Theatre's "Musicals in Mufti" and City Center's Encores! in New York City.
