This Sunday November 21st, NBC will air a special called “Improv-Ice” and the show is sure to rock. That’s because on it, a star-studded cast of world-class skaters will perform impromptu routines to the music of Foreigner. The likes of Brian Boitano and Kristi Yamaguchi will show off their skills on the ice as the band plays some of their classic songs. Check it out Sunday at  1pm Pacific/4 PM  Eastern on NBC.
