How to play correctly this song on keyboard. The same chords are good for guitar too.

Am            F(A) 
Everybody has wisdom  
Em(G)         G(B)
Everyone understands
Dm(A)            F(A)
Food when we are hungry
     C(G)           G(B)
The touch of loving hands

No-one is anyone's property
No-one should be a slave
The joining of hearts in free will
Begins a tidal wave

Now the chorus

C(G)       D(A)
Don't hold back
      Bm                  C
Don't think that hope is pointless
C(G)                D(A)       
Love is a love is a love is a love is
   Em(B)
An open door

Don't believe
That life is closed against us
Love is a love is a love is a love is
An open door

And then you have to play the chord sequence that begins with Am

And it doesn't make any difference
The colour of anyone's skin
We need the rejection of prejudice
Let peace come flooding in

Jealousy is just a parasite 
Hatred is disease
Respect for human dignity
Become skittering wind blown leaves

Chorus

The time is surely coming 
When we could all be free
When eyes for so long blinded
In opening shall see

That children may grow happily
Safe in the love of all
The earth a fertile garden 
Where nobody need crawl

Chorus

Now the solo! Play these chords during it

Am F(A) Em(G) G(B) Dm(A) F(A) C(G) G(B) x2
C(G) D(A) Bm C D(A) Em(B) x2

And if it seems that your hoping heart
Has led you into pain
Take a tip from the carpenter
Forgive and love again
And again

Continue with the chords of the verse for one time and end with G6
