Milwaukee and Hartford shows," a tour spokesman said.  "They are as
disappointed as anyone that they won't be able to perform as scheduled.  These concerts are extremely complicated stage shows with a multitude of special effects, dance numbers, and lighting and sound cues, and unfortunately we need to take a few days off to work out some technical problems."

Holders of tickets to the cancelled concerts will be entitled to full refunds. They should contact the box office or agency where they pur chased their tickets for details.
