Wednesday: Sixto Rodriguez was a late 1960s/early ’70s singer/songwriter who was forgotten everywhere except South Africa. He became something of a mysterious but beloved cult hero there, and, in the late 1990s, a couple of obsessive fans tracked him down in Detroit and brought him to South Africa for a series of big-room concerts. It was all captured on film and became the subject of the Oscar-winning documentary “Searching for Sugar Man.” The 2012 movie, appearances on Letterman and Leno and, of course, the Oscar have created an audience for Rodriguez, 70, who sounds a bit like Cat Stevens with a protest streak.
