The song he’s written for Jun and Arthur is called “55%.”
It goes like this:
Think of life as a battery
Ticking backwards slow
Instead of being 37
We’ve got 55% to go
Think of all the time
We’ve practiced and rehearsed
For an ending that never started
For the other to strike first
We gotta hurry up and love
We might not have much time left
Give or take—45 years
Of not being dead
I have so many questions
While we’re still alive
I’ll never know you completely
And it tears me up inside
We met in the wrestling ring
We were young and we brawled
I got to gently unmask you
And tell you what I saw
Not a savage beast
With a heart made of metal
When you waved the white flag
That’s when you won the battle
We gotta hurry up and love
We might not have much time left
Give or take—45 years
Of not being dead
