Celine Dion invited the families and survivors of the massacre at Columbine High to her Denver concert Friday and sang “Let’s Talk About Love” with the high school’s chorus singing back-up. When the song ended, she turned to the front row, where families and survivors of the shootings sat. “You know, we do a lot of shows, but this show has a different feeling,” the pop singer said to a hushed crowd of about 20,000. “Your pain and suffering were felt around the world. Everyone grieved with you, everyone prayed for you, everyone wanted to comfort you and everyone cared. And they still do.” Dion donated her proceeds from the Denver stint to the victims’ relief effort.
