The ghost of Johnny Cash visited this guy in his dreams and helped him write a song called "Johnny Cash is Dead and his House Burned Down."
That is indeed what this site claims.
Apparently the Cash estate is okay with this.
Which means variations of the following conversation must actually be taking place.
"If you don't object to our claim that your dead client wrote this song, we'll give you half the publishing."
Expect new works from Elvis Presley and Jimi Hendrix.
A joke I wrote with Rodney Dangerfield.
