School song
The school song is : 
   
Day by day, in high and low  
Forward we shall go
Forward like a streaming flow 
Hand in hand we go
Helping and upholding
Lowly, weak and poor
Whether be it day or night 
We shall do the right.

Chorus: Serving and rejoicing 
St. Marians' we go
God in man abiding
Before whom we bow
 
While in study or in play
Praying all the way
Watching, waiting in the way
Lest we go astray
We shall render honor
Glory every hour
This the school we love the most
With the pride we boast

Morning Prayer
Father, we thank Thee for the night,
And for the pleasant morning light;
For rest and food and loving care,
And all that makes the world so fair.

Help us to do the things we should,
To be to others kind and good;
In all we do, in work or play,
To love Thee better day by day
