Aqua, I am going to keep a check tonight on both the PBS stations and if I find it, I will freepmail you! At the moment the Celtic women are on!
Just finished watching Celtic Woman sing 'Amazing Grace' on PBS and it was the best version I'd ever heard, they sing like angels. They'll be preforming at the Fox Theater on 2-16 but don't think I want to make another trip down there so soon.
Will watch again tomorrow night to see if the Rockettes will be on PBS.
