One of the podcasts I really like is a program by two guys in England called Top of the Pods.
I recorded a short comment and emailed it to them. They played my comment recently on one of their shows. I have included the part with that comment. It runs 49 seconds. Click this link to listen (or right-click to save-as): John on Top of the Pods
