A couple of things..
First time I went to a nighter, on the train, on my own, got there, went in the pub across the road for a pre-event drink, and complete strangers made me welcome. Some of those guys I still know 35 years later.
Second thing: If your gonna have documentries, films, books etc. then the culture is opened up to a wider audiance who might not just get it. Let us face it, debating what 'it' is seems to be soul source's main function and there is a lot of knowledge scattered about on here..
I think I side with the school that says if you have to have it explained you'll never understand.
