Original London Cast these are my children from the musical fame

In times of trouble
When all the world seems, oh, so dark
And I can't find
a way to cope
When deep inside me
I can no longer feel the spark
And I can see
no ray of hope
When I am lost
What makes it all worthwhile
One simple thought
to make me smile
These are my children
My saving grace
I see my calling
In every face
These are my children
My family tree
And I thank God
And I thank God
For choosing me,
for choosing me
I wasn't blessed
As other women in this life
To have my own
to be mother and wife
But I was blessed
Beyond where wildest dreams can reach
For I have the privilege
the privilege to teach
These are my children
My saving grace
I see my calling
In each and every face
These are my children
My family tree
And I thank God
And I thank God
Yes, I thank God
For choosing me
For choosing me
These are my children
