"Amazing Grace" is a Christian hymn, and one of the most recognizable songs in the world. No one, however, has performed it quite like Il Divo - the multinational vocal group assembled by English TV celebrity, Simon Cowell. The group is made up of French pop singer Sébastien Izambard, Spanish baritone Carlos Marín, American tenor David Miller, and Swiss tenor Urs Bühler. Even though they come from different places, it’s clear that their voices were made to sing with one another. This particular performance took place in Pula Arena in Pula, Croatia, which made for an even more spectacular evening of music. The addition of the bagpipes made it that much more special and heartwarming.
