The cast, like a fine soufflé, is full of first rate choices and rises to the occasion in exactly the right way. The singing here is glorious. The Gershwins make a lot of demands upon singers and Williams ensures that every note is hit truly and that the froth and bubble in the music is given full release. The dance routines in Nice Work If You Can Get It, Stiff Upper Lip, I Can’t Be Bothered Now, French Pastry Walk and Fidgety Feet are effortlessly engaging, thrilling to watch. As you emerge from the auditorium, it is impossible not be cheery.
