Here's the transcript:
Someone asked me once if I remember how it all went down.
As if it happened so long ago that anyone could ever forget.
So yeah, I remember. I remember when our homes and our towns turned into graveyards. When the wilderness became our only hope for survival. I remember when the planes fell out of the skies, when the trains stopped running, when the turbines shut down, and the world went dark. I remember when they put up the razor wire, like it was going to stop anything, and the Feds ran out of body bags, and some of us lost our minds. Some lost more than that, much more. I remember when we lived by a code, when brotherhood meant something, and living meant more than surviving. See, ah, I remember when it all went down. Now I don't give a damn about any of that.
You know what I remember most? Riding the open road, the smell of your hair, the touch of your skin. I remember you, but those days are gone. Now, I'm a drifter, a bounty hunter, a mercenary. And for me, the broken road is all that's left. But I'll always remember.
End of transcript.
One thing I just want to say. The phrase "it went down" can have several meanings. One meaning is that something physically travelled to a lower location. That meaning does not apply here.
Another meaning is that something stopped functioning, such as 'the car went down" meaning the car is broken, it won't move. That is one of the meanings that applies to this video, in this case society stopped functioning, or "went down".
A third meaning of "it went down", as in "how it went down", means that an occurrence happened and the speaker is giving you the truth about how it happened, as opposed to lies and distortions given by others. That is the other meaning of "it went down" that applies to this video clip-the narrator is saying that he remembers what really happened that forced society to stop functioning, as opposed to untrue versions that others might be saying.
