Found this post http://bit.ly/UcbQR5 about CLP, "Each performance features a celebrity reading the nativity story and hundreds of singers from choral groups throughout Southern California. Almost 20 groups from Inland schools and churches are participating this year, some for as many as six nights." Tonight: John W. North High School Chamber Singers, Riverside; Woodcrest Christian High School Chamber Choir, Riverside. And the post lists all the various choir participants for every CLP night. Update: I just realized that this post concentrates on the Inland Empire choir participants while there are many other choirs participating. I can't find a full list of all choir participants... still searching Google.
