I found this recently on WhatTheFolk.net:
The Flight of the Conchords and HBO have agreed to a second season of their Sunday night comedy television show, starring New Zealand folk duo Bret McKenzie and Jemaine Clement. The current season has three episodes left, and looks set to have special guest appearances by Todd Barry and Demetri Martin!
Awesome! I LOVE this show and I’m so psyched that there will be a second season. Last night, I saw that there were only two episodes left of season one and I was really hoping they would do a second season. Now this news makes me super happy.
