The YouTube comments on this song say everything you need to know:
"Top 10 Crossovers Nobody Expected: Canadian folk music and the Wiggles."
Yes. That's Emma from The Wiggles. And she visualizes a song about recognizing the light in someone else that they might not see in themselves well. Not that the lyrics needed the help.
If you aren't Canadian, chances are you haven't heard of The East Pointers, a delightful folk group from Prince Edward Island. Juno Award winners in 2017, if you know anything about Canadian geography, you'll understand their name. Even if you aren't, you can't help but smile when you hear this song.... can you?
(Update: 26 January 2021): I don't often update posts this quickly, but 1) this song is so amazing I wanted to post a 2nd version of it and 2) I wanted to answer one question I've gotten more than once from our mostly American audience. Emma is using AUSLAN, which is Australian sign language, and not ASL, or American sign. That's why you don't recognize all the signs.
Now enjoy this live performance.
