It was hard not to become obsessed with Robert Smith’s head. Time and thinning hair has made his trademark tangle harder to pull off. Someone on Twitter thought it resembled Spanish moss, but I replied that was unkind to moss. It left me wondering if he has a round head, and how far back the male pattern balding starts. I don’t write this to be unkind, but watching Smith move methodically and unhurriedly through the first 20 minutes of The Cure’s set invited a consideration of him. What’s he like at home these days?
