On this day in 1980: During an Eagles concert at Long Beach, California, tempers boiled over between Glen Frey and Don Felder, who spent the entire show describing to each other the beating each planned to administer backstage. “Only three more songs until I kick your ass, pal,” Frey told Felder. The group’s next album was mixed by Frey and Felder on opposite coasts after the two decided they couldn’t bear to be in the same state, let alone the same studio.

On this day in 1985: The Eurythmics had the #1 position on the U.K. singles chart with ‘There Must Be An Angel, (Playing With My Heart). The song which was the Eurythmics’ first (and to date only) #1 U.K. single features a harmonica solo by Stevie Wonder.
