Overall, it was a reasonably enjoyable evening. Dominic Armstrong (who played Candide) and Anne-Carolyn Bird (who played Cunegonde) both have fine voices. Jason Alexander, despite being best known for playing Seinfeld's sidekick, George Costanza, does have serious musical theatre credentials, as well as excellent comic timing.
I fear that having just seen this will only reinforce my already annoying mental habit of responding (not, in general, out loud) "for an auto da fe" whenever I hear the phrase "what a day."
By the way, I tried using metro and the shuttle bus to get to Wolf Trap this time. That worked reasonably well, but I had an extremely long wait for the train to Vienna when I got back to West Falls Church. Overall, I think the transit time is a wash, though not driving late at night when I'm tired is, of course, a good idea.
