I thought she did great, too. ("Oh Canada" singer)

k.d. lang does my favorite version of Hallelujah, even if it was a sort of non-sequitar. But it is definitely Canadian, and Leonard Cohen definitely belonged in front of everyone's ears. When I saw her, I first though she should give the suit back to Wayne Newton, but the white worked, and it all made sense when the FX doves flew up through the audience. May have been religious or just universally understood symbolism. White, light and doves...

The FX, I think consisted of projection and LED lights. There were lights all over, I think and the audience members all had them, and the announcer said the person doing the lighting (can't remember his name) could virtually paint what he wanted with those lights. Amazing.
