I came upon this wonderful Finnish tune, Juokse sin humma. The video is Dan Palmquist and the Arvika Blues Band. Tuta plays a Gambian xylophone. I have no idea what any of it means, but it has gotten into my head and won't go away. I hope I can inflict this on some of the rest of you.
The original is also online, sung by Tapio Rautavaara.
