The dates have been listed on that sight for at least 4 weeks now and I think even before that. I've known for awhile that it is coming near our city and tickets are even listed as ON SALE NOW for the one theaters it is coming to here.
Good Luck to everyone who auditions! My daughter had the time of her life when she auditined in April of 2005. She still keeps in touch and has met up with many wonderful girls.
