hey praveen you can not force someone to sing what-ever you feel like.
It's all about personal freedom, and self respect.
I don't know how many of us love our parents(who probably should be equal to the mother-india), A fine example of it we claim we are the young population, but no one tells the truth that we dump our older to pathetic conditions and feels regreted on that.
Ohh what a lovely Young population of india.
Based on these statement,
I think no one has any right to force/request others to sing your National Song.
