Can you imagine seeing something like this during your ordinary, mundane commute? This exciting Irish dancing is sure to brighten anyone's day. Usually known as Irish dancing, this routine is actually an Irish step dance. Although it has its roots in tradition, this kind of step dancing is a relatively new style. While choreography varies, it is characterized by stiff upper bodies and quick, complex footwork. Irish step dancing has had many enthusiasts since its development in the 19th century, but the performance of "Riverdance" during the 1994 Eurovision Song Contest was responsible for a renewed interest in the style. Since then, the team behind the act has had huge success, including additional worldwide productions.
