Anybody see their appearence on 'One Night Stand' on HBO? I think they are one of the most hilarious musical comedy groups right up there with Tenacious D and Stephen Lynch. Although their comedy style reminds me more of Demetri Martin.
Here's a link to a few of their songs from '1NS' incase you haven't heard 'New Zealand's 4th most popular guitar-based digi-bongo acapella-rap-funk-comedy folk duo': http://www.whatthefolk.net/soundandvision.htm
