If you, like me, have the amazing sound of k.d.laing singing Leonard Cohen's Hallelujah going round and round in your head (it's a wonderful thing, but amazingly persistent), you can download the version from the opening ceremony of the Olympics on ITunes. For $1.29. Definitely worth it.
I played it before students came in to class this morning, at full volume, then again during Savasana, more quietly, and it was truly beautiful, in that way that gives you goosebumps.
(Here's a link to an earlier version. Still beautiful.)
