WTTW public television is broadcasting a new special, Celtic Thunder: Storm, on Tues. Aug. 23 at 7:30 pm CDT. This is a never-before-seen early performance by the group, filled with spectacular original numbers and powerful ensembles, the story of a man's journey through life. It was the second special they filmed, but it hasn't been seen anywhere...until now. Tickets to a Dec. 11 Rosemont Theatre concert will be pledged during the show.
