So much fun. Nearly everyone sang along with the musical, and stuffed bunnies got thrown, Rocky Horror-style, at the appropriate time. I ended up with one of them, and boy was I glad of it during "Hush". Possibly the scariest 45 minutes of television ever made.
Apparently there is a Joss Whedon night once a month (or every two weeks, I wasn't clear), Buffy (the musical and two more episodes) alternating with Firefly (playing through the series from the beginning). I may have to get to more. Although much as I love the musical, I may get tired of seeing it once a month. We'll see how it goes.
Also, I don't have to work tomorrow! And it's a mighty cute stuffed bunny. So it was a good night.
