It is an anagram for Jim Morris name. He said he was going to be reincarnated and come back as Mr. Mojo Risin. BAND FACTS What does "Mojo Risin" mean? The word Mojo has its roots in voodoo but was adopted into the early blues culture and refers to one's sexual prowess. Jim Morrison created an ingenious anagram of his name by re-arranging the letters to spell "Mr. Mojo Risin." He sang that phrase repeatedly in the bridge section of the song "L.A. Woman." The ever-accelerating tempo that John Densmore plays under Jim's lyrics in that section of the song creates a rhythmic analogy of intercourse. Rumors have persisted that if Jim Morrison had indeed faked his death, then he would contact the remaining members of the band using "Mr. Mojo Risin" as a pseudonym.
