I for one am glad this is a show I didn't miss... I was there as well...my friend shot the video there.  The night before was my first time seeing Grace live, and quite honestly, hearing her at all, for the most part.  I am a Grace fan now, needless to say.  I heard the day after that Derek asked her to sing the whole set with them, but she couldn't.

Anyone who wants to see more from that night, check out my youtube page, as well as a couple others who have footage from the show

Cheers!
