Continuing its "Delicious Dames of Broadway" series, San Francisco's 42nd Street Moon company will stage Irving Berlin's Call Me Madam Nov. 25-Dec. 20, 1998. The Washington satire, about a socialite who becomes an ambassador, originally starred Ethel Merman in the lead role of Mrs. Sally Adams. Meg Mackay will play that part in the 42nd St. Moon production.

The 1950 show won Merman a Tony. The score includes such songs as "You're Just in Love," "It's a Lovely Day Today," and "Hostess with the Mostes'."

Currently, 42nd St. Moon is presenting the seldom-produced Cole Porter musical Nymph Errant. The show, which opened Oct. 29, runs through Nov. 15.

Nymph first open in 1933 in London. The story follows a young Englishwoman's worldwide search for love and adventure. Errant indeed, she embarks on romantic sprees with men from Paris, Athens, Venice and Turkey. The work's racy nature almost ran afoul with the censors, but producer Charles B. Cochran forged a deal in which the script would pass if a scene in a German nudist colony was excised. It was, and the show went on with Gertrude Lawrence in the title role and Agnes de Mille doing choreography. The score, which Porter called his best, contains "Experiment," "It's Bad for Me," and "The Physician."

Greg MacKellan directs the Moon mounting. Caroline Altman stars.

Performances take place at the New Conservatory Theatre Center at Van Ness and Market. For information on 42nd Street Moon, call (415) 861- 8972.
