Capo on 5th
Intro - C Am7 Dm7 G

C
Let me in 
Am7
with the flowers 
Dm7
don't bring me down 
             G
I'm on the ground 
C
Let me in 
Am7
you got the power 
Dm7
to kill the pain 
                      G
I'm feelin' deep within 

              C
Last night I hurt you so 
Am7                                            Dm7 
but 'till the mornin' sun grow cold and rivers flow 
             G
I promise you my heart 
C
and we can make love grow 
Am7
until the moon up high deserts the sky
Dm7 
I know 
G (pause)                   C
you'll never face a broken heart 
Am7
No doubt about it 
Dm7
I wanna win 
         G
you back again 

C
Let me in 
Am7
your darkest hour 
Dm7
just take my hand 
               G
and try to understand 
         C
I know I hurt you so 
             Am7                                Dm7
and till the seas run dry I'll worship you and more 
                 G
I promise you my heart 
           C
now we can make love grow
           Am7                              Dm7
until the lovers cease to dream and have no heart 
           G         F     G
my lovely lady we'll never part 

           C              Am7           Dm7    G
Now we can dance upon the sweetest love refrain 
           C                  Am7
you're my tomorrow and you're my today 
     Dm7           G
now only you can show the way 
         C                 Am7           Dm7  G
through fire and rain I'm feelin' pain so much 
              Em           Am7  
you're such a part of me I want you back 
Dm7                G
hey! It's good to see you again 

(Use Stanza I Chords)

No doubt about it 
I wanna win 
you back again 

Let me in 
to feel the fire 
let love unfold 
my body's wet and cold 
I'll never let you go 
until the sand rolls in the desert 
day by day 
I promise you my heart 
and we can make love grow 
until the day no longer turn the night away 
my lovely lady in love I'll stay 

          C              Am7           Dm7    G
Now we can dance upon the sweetest love refrain 
           C                  Am7
you're my tomorrow and you're my today 
     Dm7           G
now only you can show the way 
        D               Bm7           E7  A7
through fire and rain I'm feelin' pain so much 
              F#m           Bm7

Hey! Babe 
lead me through the colors of your rainbow now 
you gotta understand 
you got this shadow hangin' over me 
I'm not the man I used to be oh! No 
my destiny is in your hands 
I know your heart is sad and blue 
I'm lonely too 
so what's the use it's no excuse oh! No 
you got a winnin' hand 
so honey come on 
Let Me In....
