These are wonderful! I had a huge smile watching these in the middle of the night, when I found them on here.
It just shows how amazingly global our world is now we have the internet. These have been choreographed by dancers in the UK - Ron Bloye and Karen Kennedy, and picked up by dance groups in Taiwan. I love the sparkly outfits and lights. I always admire dancers that can follow steps. I'm absolutely useless at it, even though I love dancing.
Here is the original by Karen Kennedy's group in Scotland. Red Sun is clearly as an ideal line dancing song.
