Since "saying" is singular in your question, I assume you are looking for a one liner rather than a multi-line cheer..
I would go with:
The [Name of your School] Indians
-------- The Spirit Is Alive ----------
For a multi liner:
We're the [Name of your school] Indians, Our color is maroon
We march to our own drummer and we sing our tribal tune
Our backs are a flash of lightning, our line a block of steel
Better have your act together when you meet us on the field
