I found this music video on YouTube, It was shot with one take, I am sure they have a lot of planning and many takes before the final take, but I must say that was very amazing and some great camera works that went with it.YouTube - LIPDUB - I Gotta Feeling (Comm-UQAM 2009) (http://www.youtube.com/watch?v=-zcOFN_VBVo)

I watched a few of these lipdubs last week, seems to be a popular concept in Canada. Really fun for all involved, from the looks of it.

The surreal version is the one shot at a hospital--can't imagine how they pulled that off what with those sick people needing care and all (possibly a comment on national health care...!)

Can't find the link to that one at the moment, maybe someone else can.
