I think i found another peak detailing in this scene...

In this scene the lyrics are : "Tune khel aisa khela, teri yaad me jaagu raat bhar, Baazigar O Baazigar"
I think this lines are dedicated to Aalam Bhai sacrificing for his country, referring him as a Baazigar!! And like Hamza is saying "He will always remember him(teri yaad me jaagu raat bhar)"
