When their mother, Felicia, slipped into a coma after being struck by a drunk driver in 2007, the Cole siblings (Michael, 17; Avery, 13; and Nadia, 9) of Highland took to singing at her bedside. (Eight months later, Felicia awoke.) Recognizing their talent, the trio visited hospitals and nursing homes in an effort to brighten the days of other patients — and the rest is history. After bringing judge Sharon Osbourne to tears with their rousing a cappella version of “God Bless America” on America’s Got Talent, the Voices of Glory are now the nation’s feel-good story of the year. As of press time, they’d reached the final round of the show — and aren’t looking to slow down just yet. According to their guidance counselors, these young celebrities are personable pupils who have been involved in their school’s choir programs throughout their academic careers. In June, they even went home to sing at high school graduation. How’s that for hometown heart?
