.

[Intro]
Bmadd9   F#7   Gmaj7   F#7

[Chorus]
Bmadd9             F#7
When I was older
Gmaj7
I was a sailor
F#7
On an open sea
Bmadd9             F#7
But now I\’m underwater
Gmaj7
And my skin is paler
F#7
Than it should ever be
Bmadd9
Mhm

[Verse]
Bmadd9               F#7
I\’m on my back again
Dreaming of a time and place
Gmaj7
Where you and I remain the best of friends
F#7
Even after all this ends
Can we pretend?

Bmadd9
I\’m on my—
F#7
I\’m on my back again
It\’s seeming more and more
Gmaj7
Like all we ever do is see how far it bends
F#7
Before it breaks in half and then
We bend it back again

[Pre-Chorus]
Bmadd9
Guess I got caught in the middle of it
Yes I\’ve been taught, got a little of it
F#7
In my blood, in my blood
Gmaj7
Memories burn like a forest fire
F#7
Heavy rain turns any funeral pyre to mud
In the flood

[Chorus]
Bmadd9           F#7
When I was older
Gmaj7
I was a sailor
F#7
On an open sea
Bmadd9                         F#7
But now I\’m underwater
Gmaj7
And my skin is paler
F#7
Than it should ever be

[Bridge]
Bmadd9
I\’m watching movies back to back.
In black and white, I never seen anybody do it like I do it any better
F#7
Then going over you, I\’m overdue for no endeavors
Nobody lonely like I\’m lonely and I don\’t know whether
Gmaj7
You\’d really like it in the limelight
You\’d sympathize with all the bad guys
F#7
I\’m still a victim in my own right
But I\’m the villain in my own eyes, yeah

[Outro]
Bmadd9 F#7
When I was older
Gmaj7
I was a sailor
F#7
On an open sea
