Chorus:
Got a secret
Can you keep it?
Swear this one you'll save
Better lock it, in your pocket
Taking this one to the grave
If I show you then I know you
Won't tell what I said
Cause two can keep a secret
If one of them is dead…
Why do you smile
Like you have told a secret
Now you're telling lies
Cause you're the one to keep it
But no one keeps a secret
No one keeps a secret
Why when we do our darkest deeds
Do we tell?
They burn in our brains
Become a living hell
Cause everybody tells
Everybody tells…
Chorus X1
And the next part is exactly the same, pretty easy.
