This song is made of 3 chord riffs, the verse, bridge and the chorus.
I think this is right because it is easy to find out. It can be played
On piano or guitar.

Verse:
G                          C
Imagine there’s no heaven,

G, C,    X3

Bridge:

Em, Am, Am7, D7, G     x1

Chorus:
C, D, G, G7, C, D, G

That’s how it go, easy or what.

The Lyrics are:

Imagine there's no heaven,
It's easy if you try,
No hell below us,
Above us only sky,
Imagine all the people
living for today...

Imagine there's no countries,
It isnt hard to do,
Nothing to kill or die for,
No religion too,
Imagine all the people
living life in peace...

Imagine no possesions,
I wonder if you can,
No need for greed or hunger,
A brotherhood of man,
Imagine all the people
Sharing all the world...

You may say Im a dreamer,
but Im not the only one,
I hope some day you'll join us,
And the world will live as one
