The music for the piece was written by guitarist
Robbie Robertson. Total authorship is typically credited solely to Robertson, although the lyrics, according to
Levon Helm, were originally improvised by Helm and
Richard Manuel, telling the story of a man who becomes sick when he is spurned by the woman he loves. Robertson has since said the lyrics were nonsensical, used only while the instrumental tracks were recorded. "I'm not sure that I know the words to 'Chest Fever'; I'm not even so sure there are words to 'Chest Fever'." He has also stated the entirety of the song does not make sense. =="The Genetic Method"==
