My daughter loves them, and I couldn't stand them till I saw that special.
Good stuff!
Both of my kids loved them, especially the oldest son. When they came to Oak Hollow Mall in High Point (NC), he went to see them and was the last kid in line to have his picture taken with them. They were very polite and, since he was the last kid in line, they spent a little more time with him and each one signed his video case and they all took several pictures with him. He still has that collection of pictures in a collage.
As much as I thought they were hokie and as much as they annoyed me listening to their songs every day, they were not shy about singing CHRISTmas songs and never apologized for their beliefs. They also didn't push enviro-whacko agendas or allow outside fringe groups to dictate how they related to the kids.
All in all, they are one of the best kids entertainment groups out there and I am sure this is tough on Greg. Seems like a good guy who genuinely loves making kids happy.
IIRC, he and the rest of the guys had their own kids participate in several of their acts and his daughter is one of the most beautiful, vivacious little girls I have ever seen. She is a real cute kid and seems to love performing. I think their wives also play a lot of the characters as well.
