I forgot where I stole this from but if you've never seen this kind of stuff live, you should if possible - back in the day our fire department sponsored a Highland dancing group (my father was head of the committee) - it was absolutely amazing - similar to this but all young talented girls that gave several performances throughout Dairy Week in the 90's (albeit to classical Scottish style music)
My nieces performed Irish step dancing. It was amazing to watch such talented young people. My nieces started at ages 5 & 7. Kept at it until they graduated college
