They were absolutely wonderful.
They were nearly the same on the panel as they are on screen, and just a general joy to listen to (and the songs!).
Last year, I got the opportunity to ask them a question. Good grief, I was so incredibly nervous...I didn't think I'd make it up there. But...
I got over my nerves, and voila!
Also, if you get the chance, check out some clips I got from this year's panel.
