A song called "Hallelujah" was played at the end of tonight's episode. Doing a bit of digging, I find its been in Shrek, which I haven't seen recently, The OC, but I never saw any of the first series, Without a Trace series 1 which was ages ago if I did see it, and Fanrenheit 9/11 amongst others. By Leonard Cohen, sung by others also, including Jeff Buckly and Rufus Wainright.
Anyway, what I am trying to recall is what did I hear it in recently? It was only in the last few weeks I would say.
Nope, not Shrek, not seen it since it first came to the bigscreen. Same as the other programmes that IMDB lists it as having been in, I know I either haven't seen them or certainly not very recently
