How are comedy/rock duo Tenacious D (Jack Black and Kyle Gass) going to follow their failed 2006 feature film, Tenacious D in The Pick Of Destiny? Not even they know, apparently. Nor is it evident whether or not a follow-up will ever happen. I suppose it's hard to be Tenacious D in a Flight of the Conchords world. As Gass recently told Billboard:

"It's very challenging," Gass says, revealing that "we probably only have one to one and a half songs right now, and we probably need 12 to 15. It might take the rest of our lives, but I think it'll be worth waiting for."
