Soon after the Three Mile Island nuclear accident, during March 1979, Browne joined with several musician friends to found the antinuclear organization Musicians United for Safe Energy. He was arrested protesting against the Diablo Canyon Power Plant near San Luis Obispo. His next album, "Hold Out" (1980), was commercially successful and his only number 1 record on the U.S. pop albums chart. The album generated "Boulevard". In 1982, he released the single "Somebody's Baby" from the "Fast Times at Ridgemont High" soundtrack, which became his biggest hit, peaking at number 7 on the "Billboard" Hot 100. The 1983 "Lawyers in Love" followed, signaling a discernible change from the personal to the political in his lyrics. In 1985, he sang a duet with Clarence Clemons in a song called "You're a Friend of Mine".
