"Life Goes On"
Life goes on

And so do we
Just how we do it is no mystery
One by one
We fill the days
We find a thousand different ways
Sometimes the answer can be hard to find
That's something I will never be
I'm always here
For anything you need
Rain or shine
I'll be the one
To share it all as life goes on
We share it all as life goes on
