I think I know why we sang the National Anthem everyday at school. I want to write it again for Nigerians to read to get the impression that the lady who wrote it (It is a lady, ba? What's her name again? Shebi she was a white british lady?) wanted to convey

Stand up, fellow citizens.
Nigeria is calling you. You have to listen, and do what she says.
Nigeria wants you to serve the land of your fathers,
with love for it, showing strenght of mind, body and character, and faith that it would turn out well.
Don't forget the sacrifices and hard work of our heroes of yesteryears,
No one should, for it wasn't pointless, and it shall never be in vain!
Our goal should be to serve with heartfelt devotion, and with all the might we can muster;
to serve one nation whose only boundries
are Freedom, Peace, and Unity.

Almighty God, who created everything that we are and we know,
give us direction in this our noble endeavour
Give the right guidiance to our leaders,
and help our young generation to know the truth, about You and about life
Help all of us to grow in our love for You and for one another
Aid us in causing our dealings in life to be increasingly honesty
Living in a manner sincere and equitably dealing with others
May we seek no small goals in building our nation,
and may we continually hit the marks
to the point where our nation would be one notable
for peace and justice.
Amen

The national anthem was a group effort and wasn't written by a British woman. Even in primary school, I remember we were taught that the anthem was written by Nigerians. The original anthem we used after independence was written by 2 male Brit expatriates but has since fallen out of use.
