The legendary composer-writer-director and poet Gulzar’s battle track ‘Badhte Chalo’ for Vicky Kaushal’s upcoming biopic ‘Sam Bahadur’, which is the first song from the film will now be played during India-New Zealand cricket semi-finals.

What distinguishes this song from a lot of other military tracks in Indian cinema is that it involves several historical war cries from various regiments of the Indian Army into its lyrics. Even more, to make it as authentic as possible, the song utilises actual soldiers to do the war-cry.
