Bernie, Dorothy and That Interior Voice.

Some might call the pesky inner voice that nags us to do the right thing a conscience, others a guardian angel. In the language of Dave Frishberg, the great jazz songwriter, who is playing a rare engagement at the Oak Room of the Algonquin Hotel with the singer Jessica Molaskey, it is the singular sense of self invoked in ''Listen Here,'' his final number in the show. Accompanying himself on piano and singing in the dry, avuncular voice of a dedicated teacher imparting his wisdom to a fidgety class, Mr. Frishberg last week delivered it as offhand scripture. ''You can run, you can hide, oh but sometime, someplace, we each of us winds up face to face with that little voice inside,'' the song declares. [ABSTRACT FROM PUBLISHER]
