Well, if you didn't know, that is actually a cover version a song done a decade or two ago. I'll give you two videos, one of the original song, then the other of Blinky Bill explaining how he stumbled upon that song. Have a listen below, it's by Issa Juma.
Now that you have read that, now listen to Blinky explain his journey with that song.
