Ari [Up] was an artist and an artist needs love more than anyone, she needed loads, but I don’t know if she got enough on a one-to-one level. Everything came second to her music, even family. You have to be selfish to be an artist; your family just have to accept that. It’s not personal, it’s not that you don’t love them. What an artist gives their family isn’t routine and their constant presence, they give vitality and ideas, independence and creative thinking.

I say something provocative to Posh Boy, he threatens me with violence, and the next thing I know, Sid's whipped off his studded belt, wrapped around his fist and smashed Posh Boy over the head with the buckle end. Splits his head open. (Sid taught me this move: wrap the tongue of the belt round your hand, use the buckle as the weapon, it's important to lock your arm straight whilst you wield the belt, and do the worst thing you can think of first. That’s the only chance you’ve got.)

One day Sid turns up in the peg trousers and they're in ribbons. He'd sliced them up with a razor blade because he hated them so much but he couldn't find his jeans so when he wanted to go out he had to stick them back together. He joined the rips with loads of safety pins, all the way down his legs, hundreds of them. That’s how the ‘loads of safety pins’ thing started amongst people in clubs: they copied it, but he only did it because he couldn’t be bothered to sew his trousers up.

The good thing about shocking is that it clears the brain of preconceptions for a moment, and in that moment the work has a chance to cut through all the habits and learnt behavior of the viewer and make a fresh impact, before all the conditioning crowds in again.

We're invincible together. We have no doubt that the Slits are great and are going to change the world. We're on a mission and pity anyone who doesn’t get it.

I grew up with John Lennon at my side, like a big brother.

Musicians are our real teachers. They are opening us up politically with their lyrics and creatively with experimental, psychedelic music. They share their discoveries and journeys with us. We can’t travel far, no one I know has ever been on an aeroplane. ... whatever they experience, we experience through their songs. It’s true folk music — not played on acoustic guitar by a bearded bloke — but about true-life experiences.

Punk’ was the only time I fitted in. Just one tiny sliver of time where it was acceptable to say what you thought.

I hear a phone ringing through the thick fuzzy air. It's Thunders, asking me to join the Heartbreakers. He says to come over to the rehearsal studios right now. I’m scared but I go anyway. That should be written on my gravestone. She was scared. But she went anyway.
