They didn't treat the other composers quite as well, in my opinion. Arlen's "Over the Rainbow" was mixed oddly with Bernstein's "Neverland". And I did not care much for the arrangement of Arlen's "Dissertation on the State of Bliss" (which should be familiar to more people from Tom Wopat's recording). Neither of the two songs from West Side Story - "Something's Coming" or "Cool" - sounded quite jazzy enough for me. On the other hand, I thought Maris Wicker's performance of "Ya Got Me" (from On the Town with Comden & Green providing lyrics for Bernstein's music) was excellent and the percussion accompaniment that Lonny Smith provided for that number was amusing.
Even with a few weaker numbers, all in all, my only real complaint about the show was that it was a bit too short. I could have used a little more banter between songs to get things up to a full hour.
