How Bob Seger Created the Eagles' Iconic Chorus in 1978: The Story Behind "Heartache Tonight"

Bob Seger was responsible for the unforgettable chorus of "Heartache Tonight", the Eagles' hit song from *The Long Run* (1979). Glenn Frey and JD Souther had the Sam Cooke-inspired verses, but the chorus was missing. Seger heard it and immediately created "There's gonna be a heartache tonight!". Frey was impressed: "His eyes lit up huge." The track symbolizes the collaboration at the band's peak, which was struggling with pressure after *Hotel California*. A songwriting and creative chemistry class between rock legends.
