Lean on Me by Bill Withers.

I'm not saying this is completely right, this is just how I play it.

G                 C                  G                D
Sometimes in our lives, we all have pain, we all have sorrow
G              C                   G              G/F#   G
But if we are wise, we know that there's always tomorrow
G                             C                       G
Lean on me when you're not strong and I'll be your friend
D                        G                C                  G
I'll help you carry on, for it won't be long 'til I'm gonna need 
             G/f#   G
Somebody to lean on
  G                   C              G                 D
Please swallow your pride, if have things you need to borrow
G               C                   G             G/F#      G
For no one can fill those of your needs that you won't let show
          G
You just call on me brother when you need a hand
                         D   G
We all need somebody to lean on
         G
I just might have a problem that you'll understand
                         D   G
We all need somebody to lean on
        G                    C                         G
Lean on me when you're not strong, and I'll be your friend
               D
I'll help you carry on
G                C                   G
For it won't be long 'til I'm gonna need
            G/f#  G
Somebody to lean on
          G
You just call on me brother if you need a friend
                         D   G
We all need somebody to lean on
        G                 
I just might have a problem that you'll understand
                         D   G
We all need somebody to lean on
G              C                G                   D
If there is a load you have to bear that you can't carry
G                 C                     G                G/F#   G
I'm right up the road, I'll share your load if you just call me
G/f#  G
Call me (Repeat)

You can replace G/f# with D if you want.
