"American Tune" is a song by the American singer-songwriter Paul Simon. It was the third single from his third studio album, There Goes Rhymin' Simon (1973), released on Columbia Records. The song, a meditation on the American experience, is based on the melody of the hymn "O Sacred Head, Now Wounded" and bears a striking resemblance to JS Bach’s “Erkenne mich, mein Hüter“. The song reached number 35 on the Billboard Hot 100.
