What controls what comes in and out of the cell?

Take the time to make some sense

Of what you want to say

And cast your words away upon the waves

Sail them home with Acquiesce

On a ship of hope today

And as they land upon the shore

Tell them not to fear no more

Say it loud and sing it proud today

And then

Dance if you want to dance

Please brother take a chance

You know they're gonna go

Which way they wanna go

All we know is that we don't know

How it's gonna be

Please brother let it be

Life on the other hand won't make us understand

We're all part of the masterplan

Say it loud and sing it proud

Today

I'm not saying right is wrong

It's up to us to make

The best of all things that come our way

'Cause everything that's been has passed

The answer's in the looking glass

There's four and twenty million doors

On life's endless corridor

Say it loud and sing it proud

And they

Will dance if they want to dance

Please brother take a chance

You know they're gonna go

Which way they wanna go

All we know is that we don't know

How it's gonna be

Please brother let it be

Life on the other hand won't make you understand
