[Verse]
F
It's been hot,
           C/E
Also very sweet.
        Eb        Bbm/Db
And I'm not usually indiscreet.
    Fadd9    Fadd9/E
But when he sparkles,
     Dm     Fadd9/G  Bbm
The earth begins to sway.
Csus4               F 
   What more can I say?
            C/E
How can I express
        Eb               Db    Bbm
How confused am I by our happiness?
  Fadd9   Fadd9/G
I can't eat breakfast,
Dm7add4 Fadd9/C    Bb
I cannot tie my shoe.
Csus4           F(b5)
What more can I do?

[Bridge 1]
F    F(b5)   F
If I said I love him,
Eb5                 Eb6        G/D
You might think my words come cheap
A/C#        
Let's just say
     G/B            Dm7
I'm glad he's mine awake,
  C7
Asleep.

[Verse 2]
          F
It's been hot
                F/E
Also it's been swell.
          Eb
More than not,
                 Dm     Bbm
It's been more than words can tell.
  Fadd9
I halt.
  Fadd9/E
I stammer.
 Fadd9/D      Bbm
I sing a rondelay.
Csus4              F
   What more can I say?


[Interlude]
F C Dm Dsus

[Bridge] 
F    C     Dm
I'll stay calm.
Dm/C  F  C   Dm     Bbmaj7
Un   tie my tongue.
      Am7   A7
And try to stay
      Cm7     C7
Both kind and young.

[Verse 3]
        F
I was taught
               F/E
Never brag or shout.
            Eb
Still it's hot,
                 Bbm/Db   Bbm
Just like how you read about.
  Fadd9   Fadd9/E
And  also caring,
 Fadd9/D Fadd9/C  Bbm
And never too uncouth.
Csus                   F(b5)
    That's the simple truth.

[Interlude 2]
F  Em  C/E  Eb(#5) B6  Csus4/D 
G/D  A/C#  G/B  Dm7/C  Dm7/G

[Verse 4]
         Gb
Can you tell
               Gb/F 
I have been revised?
          E
It's so swell,
              Bm/D  
Damn it, even I'm surprised.
     Gb
We laugh,
    Gadd9/F
We fumble
                  Bm
We take it day by day.
Dbsus4                Gb
     What more can I say?
