Among the many bands named after geographical locations (Kansas, Boston, Europe, Chicago), the band Asia scored big points with their catchy song, Heat Of The Moment. The creators of South Park noticed this, and paid tribute in their episode about Cartman attempting to get stem cell research legalized in order to save his friend Kenny.

You have to watch the tender sappy moments before the song begins:
