Am I off my rocker, or, does anyone else think Katrina Lenk could be a very interesting Desiree in A Little Night Music one day? She's obviously an incredibly effective actress in song (that Tony Awards performance of hers is seared on my brain) and it feels like the earthy quality she displayed would lend itself nicely to Desiree. There is of course, a wistfulness, a sadness to Desiree that I feel like she would nail. I'm not familiar with her comic chops, but I have to imagine she'd handle it well.
Also, this sounds like a great evening -- especially hearing that there will be a full orchestra instead of the usual solo pianist found at these types of events.
