Sign our agreement ( or be damned )

Sign it 

Blind under the bridge it goes 

Swept under the carpet too

The hidden and secret part 

Hush hush do not speak ill of what it is

Never let the guard down

Always speak of it to hide its mask

Around your words must sound

To fool all is the operation

The system must not fail

Like a falling rock it must travel

Keep it secret , do not say a word and let it fall to the floor.
