Chicken dance, Hokie-Pokie, Macarena, and the Electric slide are all classic wedding dances that I am sure date back several centuries at least, and should be well within any serious piper's or wedding band's repertoire.

If you are having a kilted wedding I think I would avoid any break-dancing or anything that requires handstands or cartwheels, unless your reception crowd is feeling adventuresome.

;) Glad I could help.
