The Last of Darrell's Sessions on Eco Church.
The file is very poor and can only really be made out on headphones. Apologies. There is a sound clip section at about 10 minutes in that may best be avoided for about a minute to protect your ears.
For those who can, there is a wma file on the soundfaith part of the site that is a better cleaner version, but I can't get the published one to sound any better.
