Gershwin, Porgy & Bess Suite, It ain't necessarily so

I fell asleep into a a peaceful nap at midday. I slept for 3 hours and dreamed about Gershwin music again. This time it was the snippet of Porgy & Bess Suite orchestra that I caught on CAS this Sunday morning. I was walking around a city full of nice folks and the music was moving everything. Nobody said a word.
They just smiled like friends and mimed things.
