I've only put the chords for the moment but it's quite plaisant to sing...
Intro:
C      G           C          F

C      G           C          F
All the people got to understand
C               G           
So, love your neighbour
         C          F
Like you love your brother

Well, all you need is love and understanding
Ring the bell and let the people know
We're so happy and we're celebratin'
Come on and let your feelings show

Love is all you need at the Butterfly Ball

bridge 1: B E A D

Ain't you happy that we're all together
At the ball in nature's countryside
And although we're wearing different faces
Nobody wants to hide

Love is all and all is love and
It's easy, yes it's so easy
At the Butterfly Ball where love is all
And it's so easy

bridge 2 (valse) : Bm E A D

All you need is love and understanding
Hey, ring the bell and let the people know
We're so happy and we're celebratin'
Let your feelings show

Love is all, yes love is all at the Butterfly Ball
Love is big, love is small
Love is free, love is all
At the Butterfly Ball

When you back's to the wall
When you're starting to fall
You got something to lean on
Love is everything
It can make you sing at the Butterfly Ball
Love is all, I say love is all, yes love is all
At the Butterfly Ball
