This is from a wedding I was at recently, that of a colleague of mine. Absolutely brilliant, her whole extended family in on it, her parents, uncles, aunts, cousins... they'd been practicing for seven weeks in the run-up to the wedding, and she knew nothing about it until the night itself. One cousin who lives in Australia was sent the video in advance so he could learn it for when he came over
Up there with some of the other wedding clips doing the rounds on tinternet, I reckon...
