(Composed by:  Camilo C. Gako Sr.)

I. San Isidro, Alma Mater dear
We are singing, do you hear
Always loyal, faithful ever
We will love you there’s no other.

II. May God bless us all
May you hear our call
May you shine forever more
‘Neath Bukidnon skies, San Isidro’s high
We will love you till we die.

SIHS Song

I. Crimson skies are all gone
Golden sun sets too soon
We shall wait for the moon to shine
From afar there’s a gleam
Green and golden it seems
It’s our beloved San Isidro High

II. San Isidro High
Please keep on shining
Spread the light of gold that I’m defining
Then I’ll spread the golden bell of love
For you and me
San Isidro High I love thee.
