In North America, "Part 2" became popularly associated with sports, as a number of professional teams adopted the song for use during games, primarily to signify scores and victories, or to otherwise invigorate the crowd. It is often referred to as "The 'Hey' Song," as the only intelligible word in Part 2 is the exclamation of "Hey," punctuating the end of several instrumental phrases and repeated three times at the song's chorus. At sporting events, fans often insert their own "Hey," or sometimes other chanted syllables.
