Last night's Olympic opening ceremony had many beautiful moments, including the flying boy and some of the native dancing. But what had me on the edge of my chair was k.d. lang's rendition of Leonard Cohen's "Hallelujah." It's a beautiful, haunting song-- not one I would expect to hear at an opening ceremony, by the way--and she really sold it. Last night's performance cannot be found on the internet, but YouTube has dozens of versions of the song including several by lang. There is a lovely, pure version in which she is backed by a single piano, but this one, at an awards show in 2007, comes closest to her Olympic performance.
