Terkel I Knibe Gratis Info

Wait, "Terkel in Knibe" being "gratis" might be part of a song lyric. I recall the Danish song "Terkel i Knibe" by a band, perhaps part of a cultural movement or a traditional song. Maybe it's about a man named Terkel living in Knibe, and "gratis" is a play on a phrase. Let me verify if there's a song with that title or if it's a known cultural reference.
