Just as the 1973 rock opera JESUS CHRIST SUPERSTAR is relative to the first coming of Christ, so also the 1973 rock concert THE SONG REMAINS THE SAME is relative to the last coming of Christ. The mystery of STAIRWAY TO HEAVEN is in the interpretation of the lyrics, not playing the song backwards: for this song relates to the events of September the 11th.
There are symbolic messages embedded within the lyrics of secular music (music that is bought and sold) which relate to the last coming of the Son of man; and not only music, but in most secular work. It is the good pleasure of the Father in heaven to present the second cherubim of glory in a rock-n-roll outfit, which relates to Isaiah 51: 1-3 and Revelation 11. Know this: As Mexico is Benjamin, so likewise Britain is Judah; hence you have Plant and Page, which signify the Lion of the tribe of Judah and the Word of God; and there are many other cymbal-ic riddles for you to comprehend.
