K. D. Lang and "Hallelujah" were on youtube for a few minutes, but it was quickly withdrawn.

Hear Leonard Cohen sing it on youtube. I don't like this particular effort; he has done it without the BOOMS of that support group which detract from the song.

The 2-cd set of K. D. Lang, "Recollection," has two versions by her. Or be a big spender and get 3-CDs plus a DVD, "Recollection" Deluxe. Two versions plus the one on the DVD.
