Having a bedroom redecorated and the decorator has stripped the wallpaper to find these mysterious messages! Pat Tate could obviously just be someone's name (although it wasn't the surname of the people we bought the house from, or as far as I can find out, previous owners), and a quick Google says was a drug dealer who was murdered and whose story was then fictionalised see here.
But no idea what the other wording means - could be "but I'm also anchormam" or "but I'm also anchorm am". Or a spelling mistake for "anchorman"?
Any ideas?!
