Not the usual wedding song - but it got them dancing in the aisles at a wedding that's become an internet sensation.
Gary Richardson, 48, from Hoyland, tied the knot in unforgettable style with his bride Tracy, 37, in Blyth, Nottinghamshire, when their three-minute 'flashmob' wedding video went viral. It has had more than 300,000 hits on YouTube.
Vicar Rev Kate Bottley declared the couple man and wife then stunned the traditional church congregation by breaking into a disco dance routine to club classic 'Everybody Dance Now.'
Guests not in the know looked flabbergasted as those in on the stunt - 28 family and friends - started their moves.
Among them were bridesmaid Kia Richardson, nine, and pageboy Jay Richardson, seven, both from Wombwell. Groom Gary is brother-in-law to their grandma Diane Richardson, of Timothy Wood Avenue, Birdwell. Diane also enjoyed a disco diva moment at the wedding.
She said: "Tracy sings in a choir and fund-raising group called Blucrew that raises money for Bluebell Wood Children's Hospice near Sheffield. She said she'd like the wedding to be memorable and when the vicar suggested a flashmob' she was all for it."
The 100-strong congregation at St Mary's and St Martin's also strutted their stuff to Kool and The Gang's track 'Celebration'.
