: "A Daily AntheM'' is three years old. I didn't originally write it with the intention of it being about Adam. I just wanted to write something that had a John Lennon, 'War Is Over
' quality. Then I was like, oh s---, if you capitalize that letter and that letter and that letter, you've capitalized my brother's name."
