School Song

We are proud of Grenville High
What a strong and blessed tie.
With all diligence and cheerfulness
We will pledge ourselves to serve.
 
We will strive for truth and honour,
for fellowship and right.
To bear the palm of victory
With courage, pride and love.
We are loyal to our great school,
to the brown, green and gold.
so to all the world we proudly cry,

we belong to Grenville High!!
