Buffy Sainte-Marie was (and continues to be) one of the great North American singer-song writers of the post-war era, but she never achieved the recognition accorded to others of her era such as Joan Baez and Joni Mitchell. According to her Wikipedia article she was subject to active and personal censorship during the 70’s by Lyndon B. Johnson and his government.
Here are three very different samples of her work, taken from her 1965 album “Many a Mile”, which was I think the third LP I ever bought. The first tells of the innocence of young love, the second the exact opposite, and the third something somewhere in between.
