Michigan Tech has both an official fight song and an official Alma Mater. At most sporting events, however, both the "Engineer's Song" and "In Heaven There Is No Beer" are played by the Huskies Pep Band, and many students consider these to be the unofficial school songs. The "Blue Skirt Waltz" is played at home ice hockey games and is called the "Copper Country Anthem." During the song, the fans join arms and swing back and forth to the music.
