Back from the show, and will have to catch up on Downton tomorrow.
The show was really delightful. 10 singers, a narrator, a nine-foot concert grand, and a string bass. I imagine it is sort of what the Kritzerland at Sterling shows are like, albeit with a few more performers. The Gershwin songs were all great, as were the performers, and imaginative arrangements. The stage was set up at the back of the main stage, and the audience (about 300, I'd say) were seated in chairs placed on the stage, with our backs to the house. This is part of an "American Songbook" series, which would be worth exploring for the remainder of their shows.
And home in less than 5 minutes!
