The song "Caterpillar" was written by Ed about his newborn daughter Roxy, and the time she spent in an incubator shortly after her birth. Harcourt said, "It`s the first song I`ve written about her. She was a little ill and we waited for her in the hospital for the chrysalis so we could take her home." The EP is also dedicated to her.
