Elvis Costello

Elvis (to Nick Jonas): Do you ever think, "I'm really tired. I should get up and write that down, but I'll remember it in the morning"? Always write it down - there's nothing more torturing than when you don't write it down and you go, "I know I thought of a line, but I have no idea what it was." I keep a notepad by the bed, and I learned how to write in the dark, so if a line comes in my head I don't even need to turn the light on and write it.
