When the Music’s over (The Doors)
The theme is music being the fire of life. When it stops, so does life's spirit. Arguably, one of the most beautifully intense moments of any rock song is when Morrison screams, "Persian Night! See the Light! Save Us! Jesus! Save Us!"
The first two lines reference the wise men from the Bible, often referred to as the Magi. The Magi is a priestly caste from ancient Persia. On that Christmas night, the Persian Magi looked into the night and saw the Star of Bethlehem. (source)
