@djjd62,
OK I get it! This style is kind of reminiscent of Russell Guy's 1978 radio play 'What's Rangoon To You Is Grafton To Me' (which I note that Night Air replayed in 2004. I'd urge you to check it out if you can spare 40mb of download, more info here:

The shroom thing was most cool because I kept hearing little pieces of music I know, usually quite obscure stuff, so it's almost like trainspotting. Might just work through the back catalogue of podcasts.
Thanks for teaching me more about my own culture....
