What song gets you on the dance floor at weddings? [POLL]

I love weddings. I love watching two happy people celebrate. I like getting dressed up (weddings are about the only time it happens). I get to spend time catching up with family and friends. And there is a dance!

I know some people are not much for dancing, but at most of the weddings I attend, skill and rhythm are not required and everyone who steps onto the dance floor is given an E for effort!

I've noticed that even an empty dance floor will quickly be filled when people hear a song they know and has set dance moves. When a group dance comes on, many of the people who had taken up a spot as a wallflower will kick off their shoes and join in the fun on the dance floor.

This got me wondering, what is your favorite group dance song at a wedding? Take the poll and let me know!
