when in doubt, google!
Mr. Mojo makes his appearance in the song L.A. Woman. The verse goes
something like this,
Mr. Mojo Risin', Mr. Mojo Risin'
Mr. Mojo Risin', Mr. Mojo Risin'
Got to keep on risin'
Mr. Mojo Risin', Mr. Mojo Risin'
etc,etc
One thing we know for sure is that `Mr. Mojo Risin' is a perfect anagram.
Re-arrange the letters and it spells `Jim Morrison'. The only other thing we
know is from John Densmore's book.
