If you look up the word lovely in the dictionary, there she is: Kate Baldwin, with her sweet, pure voice, beautiful smile, and great charm. In her current show at Feinstein's, She Loves Him, Baldwin devotes her copious gifts to the songs of the great Sheldon Harnick, who sings a few duets with her (and one solo). The whole show is a treat as they wander through Harnick's early novelty songs, Fiorello, She Loves Me, Fiddler, and the Rothschilds. The evening has many highlights, including Baldwin's gorgeous "When Did I Fall in Love?," excellent "A Trip to the Library," and superb "Gorgeous." Harnick's voice is strong and gravelly and contrasts perfectly with Baldwin's. I particularly enjoyed their duets on "In My Own Lifetime" and "Sunrise, Sunset." Harnick sat on stage for a couple of Baldwin's solos, and if I had to pick one best moment of the evening, it would be watching him kvell while Baldwin sings his songs. Baldwin's patter is often funny, and her backup band is superb (Scott Cady, piano/musical director; John Beale, bass; and Andrew Sterman on a truly impressive range of wind instruments).
