Following a now-familiar recipe, this musical revue uses a new narrative to string together a series of classic tunes. This time, they are culled from Disney"s ample vaults. The material is impressively comprehensive. The oldest song originated in The Shindig (1930) and the newest are from Toy Story 2 and Disney"s Tarzan (both 1999). Many of the numbers are grouped in likeminded "sessions." Some focus on a single movie, like Dumbo or The Little Mermaid, while the session dubbed "Silly Symphony" is pulled from nine different flicks. Kids will be delighted by the evergreen classics, while music-minded parents will get a kick out of nuggets written by 20th-century pop titans such as Peggy Lee (cowriter of the tunes from Lady and the Tramp)and Carl Stalling ("Minnie"s Yoo-Hoo"). The cast is adept, the plot is--oh, who cares? This is all about the songs, and it"s almost scary to realize just how many of them have become part of the American collective unconscious. --Elisabeth Vincentelli
