Greenbelt has a podcast.
John Bell said that.* I’m not going to explain it.**
The two are linked.
If you subscribe to the Greenbelt podcast (click on John’s lovely bearded Scottish head for more info) you can get free Greenbelt talks; including the one where John Bell said that* then you can hear why he said that* and all will be explained.**
If you do subscribe, it’d be great if you jotted a quick review on itunes too; it helps the people who put it together to know what they are doing right and what they could do better, and it helps itunes to rank the podcast.
