So, this is just the first verse hook, and chorus. Here we go~

Strum pattern: It doesn't matter which you use, but I find D D U, U D U to be most easy.

P= strum pattern


            C (P 2x)                                                      Em (P 2x)
If you ever find yourself stuck in the middle of the sea
Am (P 1x)      G (P 1x)   F (P 2x) 
I'll sail the world,  to find you 
            C (P 2x)                                                          Em (P 2x)
If you ever find yourself lost in the dark and you can't see
Am (P 1x)      G (P 1x)   F (P 2x)   Dm (P 2x)
I'll be the light to guide you
                               Em (P 2x)   
Find out what we're made of
          F (P 2x)                                            G (strum once)
When we are called to help our friends in need
               C (P 2x)            Em (P 2x)
You can count on me like 1, 2, 3
        A  
I'll be there
F (P 2x)
And I know when I need it
            C (P 2x)            Em (P 2x)
I can count on you like 4, 3, 2
           Am (P 1x)   G (P 1x)  
You'll be there
             F (P 2x) 
'Cause that's what friends are supposed to do,
     C (P 2x)
oh yeah
        Em (P 2x)
Ooooooh,
       Am (P 1x) G (P 1x) 
oooohhh 
F (P 2x)
