And you know how it is some people have this fixation with a certain colour, and purple is one of those colours, and that is the whole archetype of these ladies, she was wearing everything: shoes, stockings, handkerchief, skirt, coat, everything, purple shades she was crazy. And one of my girlfriends, she was getting crazy, getting out of hand I was saying ‘you might as well start wearing purple now, because that’s exactly what’s gonna happen to you’. One day I just sat down with a guitar and basically just set it down with just an A minor chord and a song rolled out of it. I love it when that happens. Some songs just roll out.."
