Found this in the The Scotsman newspaper TV/Radio Guide yesterday. Not sure if it's going to be available online as I didn't have time to check.
THE FLIGHT OF THE CONCHORDS
Radio 2, 10pm
Thursday, 1 September, 2005
The Flight of the Conchords are a New Zealand folk parody act looking for a hit with Frodo, Don't Wear That Ring. This is the premise of a new comedy series starring the duo, Bret McKenzie and Jemaine Clement, and narrated by Rob Byrdon.

BTW, one of the funniest things I saw at this years Fringe Festival was last week at the Phat Cave. David O'Doherty and Demetri Martin doing their version of a Flight of the Conchords song including the intro "We are New Zealands's premiere folk parody group"!
