"I've also gotten to play in front of a million people in Central Park when there was a grass roots movement calling for nuclear disarmament - it was about 1982 - they called it Peace Sunday"

In this quote, Jackson Browne reviews a considerable event in his career and the more comprehensive social and political landscape of the early 1980s. Browne discusses carrying out in front of a million people in Central Park, New York City, throughout a rally that advocated for nuclear disarmament. This event, which he keeps in mind as being called "Peace Sunday", likely refers to one of the numerous large-scale anti-nuclear demonstrations of that age. Specifically, this was a time when the danger of nuclear conflict, notably between the United States and the Soviet Union, was a main concern in global politics.

The early 1980s were marked by increased Cold War stress, with both superpowers expanding their nuclear arsenals. In response, grassroots motions emerged worldwide, requiring nuclear disarmament and promoting for peace. These movements often organized big public demonstrations to raise awareness and galvanize public opinion versus the expansion of nuclear weapons. The million-person turnout at Central Park underscores the strength and scale of public belief against nuclear brinkmanship during this period.

By highlighting his participation in this occasion, Browne not just states a memorable moment from his musical career but also aligns himself with the peace advocacy of that period. His music and public persona have often been connected with social and political causes, and this participation reflects his commitment to leveraging music as a tool for activism and change.

The reference of "Peace Sunday" is considerable as it suggests a collaborated effort to harness cumulative energy towards meaningful change. For Browne and those included, the occasion would have been an effective presentation of solidarity and hope, embodying the goals of millions who looked for a world free from the specter of nuclear annihilation. Through this reflection, Browne reminds us of the long-lasting power of music and neighborhood in promoting for a more serene and simply world.
