Is there a version of Gravedigger by Dave Matthews that can be voiced over?

I have this assignment that I need to do where I must sing a song.
Gravedigger has been assigned to me, and I wished to know if there is
a unvoiced version that I can download or buy, or am I going to have
to start from scratch? It would make it tons easier for all of us if
there is already an unvoiced version out there, but, depends on what
you folks know.
