I have stated, on more than one occasion, that that is the greatest line in rock 'n roll.
I like the story where after Morrison has sung “Mr. Mojo Risen” a few times he says in front of the band something like “Oh wow man - you can write “Jim Morrison” using the letters from Mr. Mojo Risen.” The rest of the band all chimes in with how freaked out that is.
Of course Jim started off with his name first to get “Mr. Mojo Risen”!
