Viva Colonia is a song by the Cologne band Höhner, written in the Kölsch dialect and closely associated with the city's carnival season. Its chorus, da simmer dabei, dat is prima, roughly means we are in on it and that is great, and it quickly became a singalong staple in tents, pubs and parade crowds. Because the line is short, rhythmic and easy to join even for non-German speakers, it spread through party playlists, football gatherings and online celebration videos, where it still signals that everyone is ready to join in.
