Students from the Marjory Stoneman Douglas drama club closed out CNN’s Townhall with this emotional tribute they wrote and sung for shooting victims and their fellow students.

Here’s one verse of the lyrics:

You’re not gonna knock us down.
We’ll get back up again.
You may have hurt us
but I promise we are stronger and
we’re not gonna let you win.
We’re putting up a fight.
You may have brought the dark,
but together we will shine a light.
