[Parte 1]

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-Chorus]

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

[Chorus]

A                   E
 When you know, you know
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

[Parte 2]

                         E
A word to all my friends
     Bm7                                                                A
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

[Pre-Refrão]

        E                         Bm7
'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

[Chorus]

A                   E
 When you know, you know
Bm7
 When you know, you know
                  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
                            E
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
           F#m D E
In a minor key
                          A
'Cause when you know, you know
                   Bm7
When you know, you know

A                     E
 So if you don't know, don't give up
            Bm7
 'Cause you never know what the new day might bring

[Bridge]

A E                       Bm7
    Maybe tomorrow you'll know
                      A
Maybe tomorrow you'll know
                      Bm7
Maybe tomorrow you'll know
I mean, join the party
A           E                      Bm7
 By the way, the party is December 18
(Hey, let's waltz this out, 'cause)

[Chorus]

                          A
'Cause when you know, you know
                            E
And when you're old, you're old
                   Bm7
Like Hollywood and me
                     Bm7
That diamond on your ring
                               A
The song that you bring to the table
                      E Bm7 C#m D E
The one that makes me sing
           F#m D
In a minor key
                Bm7 E
Diamond on your ring
                          A
'Cause when you know, you know
                   Bm7  D
When you know, you know
