"Behind Blue Eyes" originated after a Who concert in Denver on June 9, 1970. Following the performance, Townshend became tempted by a female groupie, but he instead went back to his room alone, possibly as a result of the teachings of his spiritual leader, Meher Baba. Upon reaching his room, he began writing a prayer, the first words being "When my fist clenches, crack it open. . . " These words later appeared as lyrics in the "climactic rocking section" of "Behind Blue Eyes. "
