I have a client that is part of Canto Deo musical group, and every year they put on a wonderful Christmas program. They are held at various locations across the South part of Denver, and have matinees and 7 pm performances to choose from. They are free and are always packed. The program won't have pop Holiday music, you will hear classic Holiday songs. There was a children's choir too, but thought I should not post a photo from that group.
It was really cute last night after the concert was done, they invited all the children in the audience to come and "be the conductor" of the concert. Some really got into it, some were quite shy. It was too cute. Should have taken some photos of this part, but was enjoying it too much, and never thought of it.
