New Zealand's self-described "fourth best comedic folk music act" Bret McKenzie and Jemaine Clement returned to HBO for the special in October. They filmed the performance during the"Flight of the Conchords Sing Flight of the Conchords Tourâ€ at theÂ Eventim Apollo in London. They, of course, played classic fan favorites such as "The Most Beautiful Girl (in the Room)" and "Inner City Pressure." And they sprinkled new tunes into their setlist, including "Father and Son" and "Deana and Ian."For everyone hoping this recent special means more Flight of the Conchords is on the way, you can keep the spark alive. It's possible we'll still get the long-rumored Flight of the Conchords movie. If not that, we'll keep our fingers crossed for another new tour and/or special.
