I saw John Cale in 2013 but I had never seen Lou Reed and I thought "I better see Lou Reed soon," but I was too late. There is always a reason not to do something, not to see a show, not to start that novel, whatever thing you want to do but talk yourself out of. Looking back, the reasons not to do something are never good enough. A reminder to do that thing now - you don't always get a second chance.
Of all the things about Lou I read this year, this remembrance by Moe Tucker was my favorite:
