Lyrics:

When the river runs dry, what will we say
NA NA NA NA NA NA NA NA HEY HEY
In the 21st century

Oh when the river runs dry, what will we do
NA NA NA NA NA NA NA NA OH-HOO
In the 21st century

When the river runs dry, what will we wear
NA NA NA NA NA NA NA NA where?
To the 21st century

Now some people sing, Some people say
NA NA NA NA NA NA NA NA HEY HEY
Get up off your knees and pray

Pray that the earth don't tire, of the way that we're puttin her down
Hope that the universe don't say 'I'm still expanding but your time is up'

Some people sing, some people sigh
NA NA NA NA NA NA NA NA why?
Why can't we live in peace

Some people sing, Some people say
NA NA NA NA NA NA NA NA HEY HEY
In the 21st century

Hope that the earth don't tire, of the way that we're puttin her down
Hope the universe don't say - stop spinning around
Hope the world don't say that we've got no place to go
Hope the universe don't say 'I'll be expanding for a while, you? No!

In the 21st century
In the 21st century
In the 21st century
In the 21st century
In the 21st century
21st century
21st century
21st century
21st century
21st century
in the 21st century
21st century

When the river runs dry, what will we say
NA NA NA NA NA NA NA NA HEY HEY
21st century
the 21st century
the 21st century
the 21st century
Oh when the river runs dry, what will we do
NA NA NA NA NA NA NA NA OH-HOO
