Adams wrote the song when he was 15 and still at school. He recalled to Girl.com.au
"I remember it was performance week and each student had to write an original song and sing it for the class, but I had totally forgotten. So I grabbed a guitar, sat down on some stairs about an hour before it was my go and just started frantically strumming chords and came up with all the melodies in about 12 minutes and then went in a few minutes later and pretty much winged it! I ended up finishing the song after that night and kind of kept it in my pocket until the right time came to jump in the studio and produce it."
