Fans of the ghoulish group of dancing local teens, better known as the West Springfield High School Dance Team, can breathe a little easier now that Wednesday night’s “America’s Got Talent” results are in. The team was brought back this week by judge Sharon Osbourne as part of Wild Card Week after being eliminated by Piers Morgan and Howie Mandel. And good news, this time around the team made it into the show’s semifinals. The Fairfax County dance team won its second national championship in March in Orlando.
