Researcher Nguyễn Đắc Xuân recalls his encounters with musician Trịnh Công Sơn against the backdrop of the peace movements of the mid-1960s. From the unforgettable night of April 30, 1966 in Đà Lạt—when he, Father Nguyễn Ngọc Lan, and Trịnh Công Sơn shared a deep sense of “the helplessness of life”—to later memories in his Huế home filled with books, documents, and portraits of the composer, the story evokes the atmosphere of a turbulent era marked by existential anxieties, anti-war ideals, and the yearning to build peace. Through these recollections, listeners witness the convergence of different paths chosen by young intellectuals of the time, as well as the profound influence of figures such as Phạm Duy, Thích Nhất Hạnh, and Ngô Kha on Trịnh Công Sơn’s anti-war philosophy.
