What song should I sing??

Okay, so our school's gonna have sort of a buổi hòa nhạc type of thing, and it's gonna be in front of parents, teachers and students. I need a good song that I can sing! I don't know what though! Parents here are very conservative, and I assume they won't like rock music... Otherwise I would've gone with "Hello Cold World" bởi Paramore!


BUT if bạn guys think hello cold world is a song that an Indian mother/father COULD like, then...
