The Vietnam War Song Project has identified 160+ songs related to P.O.W.s, released during both the war and post-war years.[1][2] The project's editor, music historian Justin Brummer, noted that the late 1970s and 1980s saw a revival of interest in Vietnam in cultural representations, especially related to P.O.W.s. The topic was central to dozens of films of the era, including First Blood, Uncommon Valor, and Missing in Action.[citation needed]
