I recently went through my music to see if I could find anything interesting and up to date for my Friday classes or whichever other classes, where a song might fit into.
Björk’s Triumph of a Heart, e.g., in which the Islandic singer sings about the path the blood takes to the heart and how the heart then triumphs and works incessantly. In the worksheet I have included a diagram of a body to a gap fill text. Since the lyrics part is relatively short and easy, this could be used with a lower intermediate class learning about the human body.
