When the world is getting dark
There will be a light in the end
When the wheel is slowing down
We only need our family and friends
Together we stay strong
Together we belong
Finding a way to make the future better
When times are getting rough
We think we've had enough of disease
In the invisible war infecting us piece by piece
It's a challenge we must overcome
A finish when the race is finally won
And the map to guide us on our way
We will build now when the day is done
Together we unite
Together day and night
Finding a way to make the future better
Sharing a struggle brings us all together
Giving us shelter in a stormy weather
Together we stay strong
Together we belong
Finding a way to make the future better
Together we stay strong
Together we belong
Finding a way to make the future better
Together we unite
Together day and night
Finding a way to make the future better
Together we stay strong
Together we belong
Finding a way to make the future better
Together we unite
Together day and night
Finding a way to make the future better
Together we unite
Together day and night
We're finding the way
To make the future better
Together we stay strong
Together we belong
Finding a way to make the future better
Together we unite
Together day and night
Finding a way to make the future better
Together we stay strong
Together we belong
Finding a way to make the future better
