Thanks for the comment, Van Greco.
The first version is linked in the original post, if you want to make the comparison.
To answer your question, the "amateur band in a church hall" style was an attempt at gaining that peculiar sound which, I think, we have all heard. A combination of 'not too good' performance and 'not often enough' rehearsal, coupled with too many 'trying to outdo each other' individuals! It was good fun, from my point of view (being responsible for ALL the performers!), but the main ingredient to attain the sound was the use of various 'church hall' reverbs.
Thanks again for the interest.
