A                     E                       Bm7
 This is a simple song, gonna write it for a friend
                                           A
My shirt is inside out, I'm messy with the pen
                     E                Bm7
He met Margaret on a rooftop, she was wearin' white
                                 A
And he was like, "I might be in trouble"
                      E
He had flashes of the good life, he was like
Bm7
 "Shall I jump off this building now or do it on the double?"

[Pre-Estribillo]

A        E                         Bm
 'Cause, baby, if your love is in trouble
                          A
Baby, if your love is in trouble
E                         Bm7   E
Baby, if your love is in trouble

Bm7
 When you know, you know
   E              A
It kinda makes me laugh
                  E
Runnin' down that path
                       Bm7
When you're good, it's gold
                          A
'Cause when you know, you know

With their rеd fires, their white icе, their black eyes, and their blue lies
                     E                 Bm7
If you're askin' yourself, "How do you know?"
                                           A
Then that's your answer, the answer is "No"
                 E                                         Bm7
Yeah, gotta run around, around, around like your head's on fire
                   E          A
Run away like your head is on fire

And when you're old, you're old
                   Bm7
Like Hollywood and me
                    Bm7
The diamond on your ring
    E                          A
The song that you bring to the table
                      E Bm7 C#m D E
The one that makes me sing

 'Cause you never know what the new day might bring

Maybe tomorrow you'll know
I mean, join the party
