As for now, all schools are in some or the other way, going to sing the National Anthem 'Vande Mataram' of Bankim Chattopadhyay. However, some schools prefer to get the song played on a cassette whereas some schools will adopt their own easier way of singing the song and not how the well-known singer Lata Mangeshkar sang.
The National Anthem is made compulsory to sing yet, been very controversial whether to sing or not. Whatever be it, one thing is sure, the National Anthem is very rich in its words and reflects the culture of the nation India and believe me, very classical, the song itself raises your inner self for the love of the mother-land. Any country's National Anthem has to be so rich like this one and any person residing anywhere always do feel proud to belong to their own country. So will be an Indian - the National song 'Vande Mataram' is saluting the nation and in praise of the rich India.
Here's the Google video with the song in action. Enjoy!
I am Proud to be an Indian and you too, be Proud of our Nation.
Keep the faith!
