Frank Sinatra said this great thing, that singing isn't about singing in tune, or great technical singing. It's about making people believe in the story you're telling.

On my Instagram, I'm always keeping a record of things being pulled down in Soho and shutters being closed. Every city - and London more than anywhere - has got to be a vibrant mix of all different things. We can't allow it to become a monoculture.

The weird thing was that Soft Cell was supposed to have come and gone before I started the album.

I was quite naïve, a boy from Southport. When I went to art college in Leeds, I lived in a basement flat, and I heard clunking on the stairs all night, and I thought it was just nurses going to work on the night shift at the local hospital! Then I found out it was all working girls upstairs. I suppose I came from a protected background and had my eyes opened wide by that side of city life.

I was a magnet for people who want to take advantage of people like me, who think they're part of this life but they're not.

So often, the singer is the sound of the record. People think they can cover anything, but the whole voice is the thing that's unrepeatable.

I'm often prone to self-doubt about everything I do.
