The legal length of the Indian national anthem is 52 seconds.
So the next time you wonder why your local movie theatre subjects you to a extra long rendition with AR Rahman flipping his hair or are forced to see a horrendous animation of the Indian flag, just remember that the theatre owner is making sure that no disrespect is shown towards the anthem. A anthem-like song going on for more than 52 seconds doesn't remain the anthem anymore, so it really doesn't matter if someone doesn't stand up. Naa rahega baans, naa bajegi baansuri.
Very patriotic. Maybe some of our political parties should N-gage in such silent show of patriotism, rather than the tamasha going on right now.
