Jeremy Konner delivers this quite epic and hilarious six minute promo for the return of Tenacious D (aka movie star Jack Black and Kyle Gass).

With brilliant cameos from Val Kilmer, Dave Grohl, Tim Robbins, Jimmy Kimmel and Josh Grobin, the video, set up as a type of reunion, is part of the campaign to promote the release of the band's new album Rize Of The Fenix - due in May.
