The one I sang as a child was:

Sun in thy sky,
Birds flying by
This is the picture
you gave me
Far down below
Someone I know
looked up as though he would say

May there always be sunshine
May there alwayas be blue sky
May there always be mama
May there always be me

There could be Sun
For everyone
There could be worlds filled with laughter
Peace is a dream
Or so it seems
When you take my hand and you say

Chorus again (we sang engish and than russian on the chrous)
