I just got home, and it was absolutely worth it. I found myself grinning like a maniac through a lot of the show, and just watching Anthony Rapp dancing down the table in La Vie Boheme (one of my favorite songs) was worth the price of admission. Touring casts are often hit-or-miss in terms of competence and energy, and this one was very much a hit. They were a little bit weak in spots, but for the most part they stood the test of being on stage with the two superstars.
If you're in the bay area and you love the show even half as much as I do, go. But hurry, since it's only here for a few more days.
And to top it off, there was an Ebay purchase waiting for me when I got home-- an obscure recording of the musical Chess. I know, I know, that's only a treat to me and a few other theater-loving freaks. I'm OK with that. (Now, if I could just find the bootlegs...)
