Il Divo performs "Somewhere," one of the show-stopping numbers they recently sang on stage with Barbra Streisand during her sold-out tour. Barbra handpicked Il Divo to be a part of her shows.

"I've seen you in concert twice with Barbra," Oprah says. "You were amazing. The hairs on my head were standing up…and [it takes] a lot to get them to stand."

David (lower right corner) says singing alongside Barbra was an incredible experience. "If someone had told me three years ago when we started that we would be on stage with Barbra Streisand … I would have just told them they were dreaming," he says.
