End Or Just The Beginning of The Conchords

We won't know until 2009 when Flight of the Conchords comes back whether or not they've shot their load on their first full length CD. If you've seen the show, you've heard these songs. That might disappoint some who were hoping that they would hear new stuff. But this is still prime comedy/parody/satire. But you do wonder, because it's so hard to maintain brilliant beginnings when it comes to this type of stuff, will they have anything left to write about. And will they approach it with the same fervor?
