"An unfortunate altercation with some U.S. Marines forced bassist/vocalist Peter Cetera to sing the song differently. While celebrating the victory of their hometown Chicago Cubs at Dodger Stadium, four angry Dodger fans targeted Cetera not only for his team loyalty but also for his long hair. They broke his jaw in three places. Producer James William Guercio did not have time to wait for the injury to heal. The band needed to complete the recording. Cetera recorded the song through clenched teeth and went on to adapt his trademark singing style."
