THERE'S GOT to be a morning after for a singer of disaster movie theme songs. And Maureen McGovern, a former folk singer who crooned under the opening credits of "The Poseidon Adventure" and "The Towering Inferno" has reemerged as a musical theater actress and a superior cabaret singer.

Tasteful, scrupulously tasteful, is the way to describe McGovern's LP "Another Woman in Love," which is marked by careful song selection and McGovern's unadorned coloratura, accompanied by Mike Renzi's supple but unobtrusive piano.

McGovern's voice, though still pristine and precise, has become warmer since her soundtrack days, and the singer often seems to be doing a conscious imitation of Barbra Streisand's pre-pop period as she sails elegantly through 14 songs.

The record is structured like a cabaret act, opening with Blossom Dearie's adorable introduction "I Like You, You're Nice," through Stephen Sondheim's delicately description "I Remember," and a languid "You're Getting to Be a Habit With Me," and closing appropriately with the Bernstein-Comden-Green "Some Other Time." Co-produced by McGovern and Ron Barron (whose wife co-wrote three of the songs) it's as intimate as a pianoside table in a cozy nightclub.

MAUREEN MCGOVERN -- "Another Woman in Love" (CBS 42314). Appearing Friday at the Barns of Wolf Trap.
