Excellent! Some of my favorite Serenity songs are their duets. REALLY looking forward to their set! I hadn't heard that she had left Whyzdom though - I enjoyed From The Brink of Infinity. Too bad.
Ditto this. While I had a SLIGHT hope that Charlotte would come for her songs (and others), I knew it was a pipe dream. I am sure that Ms. Delauney will do a great job, and impress us all with awesomeness.
