We lost a lot of beloved celebrities in 2016, including Leonard Cohen, most famous for his song "Hallelujah."
"Hallelujah" is everywhere, from TV shows to movies, and it's also become a classic Christmas song. Thus, it was only fitting that the Killard House School Choir tackled it in their holiday concert -- and the results are mind-blowing. Far from your average group of young singers, this choir can carry a serious tune. Especially impressive is the performance by the girl in front.
