Jolson at the Winter Garden

Playing Al Jolson (1886–1950), the Russian-Jewish immigrant known in his heyday as "the world's greatest entertainer," presents a formidable challenge. Mike Burstyn, who courageously steps into the shoes of the legendary actor-singer in this generally enjoyable musical potpourri, wisely saves "My Mammy" for last. Jolson crooned this song—his signature number—in Hollywood's first full-length talking picture, "The Jazz Singer" (1927). The song provides the bravura punch needed to send audiences out on a jubilant high. One wishes that more of this pleasantly unpretentious evening elicited such a euphoric jolt.

Created and written by Burstyn and director-choreographer Bill Castellino, this vehicle is essentially a revue, though it attempts the tiniest hint of a book: Jolson in his later years returning to Broadway for a farewell performance at the Winter Garden, albeit with a not-too-surprising twist in store. This piece is clearly designed as more of a performer showcase than a bio-musical. Burstyn exudes warmth and humor, and he has a brassy singing voice suited to the material and the era. Yet there's not much Jolson in his portrayal. In "My Mammy," Burstyn expectedly takes the famous Jolson posture: on one knee, with arms spread wide. Throughout the evening, the performer sings and speaks with the bottom sides of his mouth turned down, affecting something similar to a Walter Matthau growl. Yet he never quite reaches the outlandish, over-the-top style that Jolson was known for. That should matter little to younger audiences or those unfamiliar with Jolson.

Three accomplished actor-singers (Jacqueline Bayne, Laura Hodos, and Wayne LeGette) join Burstyn in a few songs and dances, and briefly appear as myriad characters (such as George Gershwin), while snippets of Jolson's life and career quickly drift by. Among the intriguing tidbits told is the irony that one of Jolson's specialty routines was performing in blackface, while he simultaneously became a forceful advocate for racial tolerance on Broadway.

Christopher McGovern's music direction and vocal arrangements are top-notch. The visual design elements are serviceable at best. Yet any show incorporating skillful renditions of such a smashing array of song classics ("Blue Skies," "Swanee," "April Showers") from the wonder years of show biz needs few excuses.
