School Song
Togetherness shall be our watchword
Love is the key
We will defend thy name and honour
We’ll always cherish thee
Chorus
We’ll ever sing together
Songs of unity
To our beloved Alma Mater
G.S.S. dear to thee
These school days will soon be over
Gliding swiftly by
G.S.S. will be remembered
Till the end of time
Chorus
Your banner we will hold up high
Your name is exalted
A legend you will surly be
A place in history
