When I was 18, I spent one night trying to paint LATE AGAIN in big silver bubble letters on the side of a passenger train. British Transport Police showed up and I got ripped to shreds running away through a thorny bush. The rest of my mates made it to the car and disappeared so I spent over an hour hidden under a dumper truck with engine oil leaking all over me.

‘As I lay there listening to the cops on the tracks, I realised I had to cut my painting time in half or give up altogether. I was staring straight up at the stencilled plate on the bottom of a fuel tank when I realised I could just copy that style and make each letter 3ft high.

‘I got home at last and crawled into bed next to my girlfriend. I told her I’d had an epiphany that night and she told me to stop taking that drug ‘cos it’s bad for your heart.
