DR George, I think your evening sounds like fun.
When the Shakespeare Festival gave free performances of the musical THE TWO GENTLEMEN OF VERONA several years ago, my best friend Matthew and I took my goddaughter Charlotte. We sat next to Tommy Tune, the rains came, the show took a break and then continued. We left Central Park about an hour later than usual, rather wet but very happy that we stayed.
I think that production was the first revival I've seen of a show, where I saw the original production, that reached the same standard of excellence.
