Lyrics:

[Valjean arrives, dressed as a soldier.]

Joly
Here comes a man in uniform
What brings you to this place?

Valjean
I come here as a volunteer

Joly
Approach and show your face.

Sentry
You wear an army uniform.

Valjean
That's why they let me through.

Joly
You've got some years behind you sir.

Valjean
There's much that I can do.

Joly
You see that prisoner over there?

Grantaire
A volunteer like you!

Combeferre
A spy who calls himself Javert!

Grantaire
He's going to get it too...

Sentry
They're getting ready to attack
