This is very topical so I thought I'd share a compilation document of 10 audio clips.
These are mostly from before 1975, taken from convention recordings at the time, stressing the importance of 1975 and getting the crowd excited in anticipation.
Entire talks are embedded but it's been typed out what was said and the time point it occurs.
This document is 220MB, so be warned.
I hope you're not triggered by the drawn out assembly speech style because this is full of it.
If anyone ever tries to tell you that there was no mention of 1975, hopefully this will give you some evidence.
If anyone with the ability could turn this into a short, shareable video, that would be much more useable and shareable than this (no disrespect to the creator).
Click here for the recordings. It will be gone in one month.
