I related earlier that I attended a Christian school during my teen years. I sang in Mixed Chorus. The director did not dignify it by calling it a choir, but she tried her very best to elicit choir-like performances from us. I truly enjoyed participating in this thing, one of the very, very few things I enjoyed about school. This video features one of my favorite songs that we did. This group may do it with more technical skill, but they do not hold a candle to CSBC Mixed Chorus for enthusiasm!
