Story behind "Autobiography" / "Green Man" via Class of 88 website

SMILEY: The Shacklewell Arms used to be called The Green Man. And basically The Green Man pub was where all the local guys used to go and buy their crack cocaine. That’s where it was sold, in that pub, so you know that pub is responsible for smashing so many lives. I mean, tearing families apart.

Seriously, that was like the devil was there. And I mean, we’ve seen from ages of, like, fourteen year olds to fifty year olds coming out of that pub, and they’ll be stealing from mums and brothers and dads, and robbing old ladies. Doing aggravated burglaries so they could get money to go into that bloody pub, The Green Man.

I mean, that’s a significant piece of history that place is, but a lot of people don’t know this.

But we was here from the beginning. So, we made a song called The Green Man. It was about people going in there buying crack.

And also on the flipside of Green Man, where it was more PJ’s idea, we had a song called Autobiography Of A Crackhead, and that was sort of like one of our deepest songs we’ve ever done really.

PJ: Basically it was a rap tune, and it was us both doing a verse each about living the life of a crackhead.

SMILEY: It’s not, like, bigging up crack…
