Pure talent!

Amazing how so many of this cast have awesome voices! They have good mics/sound system of course, but it's live and no lip-syncing to studio voices. Some are weaker than on the show which tells which ones are being helped by tech more, but still, way better than a lot of what's out there.

Oh, and what's not to love with Amber tweaking Simon just a wee bit? *ggg!*
