In less than an hour yesterday, the Childrens Theater Company sold out tickets for a performance of "The Grinch Who Stole Christmas." It was the latest in a new CTC program "Pay what You Can", which allows buyers to decide how much to pay for tickets. The program is one of the innovations brought by the CTC's artistic Director of a year... Peter Brosius (BRO-sious.) This season is the first selected by Brosius, and to some degree it signals a move away from adaptations of childrens' classics to new works and plays that deal with modern issues. Minnesota Public Radio's Chris Roberts reports.
