Hum Kaale Hain To Kya Hua cover by Kamal

This cover song was originally sung by Rafi Sahab in Gumnaam (translation: Unknown or Anonymous) a 1965 Bollywood thriller film, directed by Raja Nawathe and starring Manoj Kumar, Nanda, Pran, Helen and Mehmood. The film is an adaptation of the mystery novel And Then There Were None by Agatha Christie.

The film came to wider attention in the Western world when its opening song "Jaan Pehechan Ho" (a Hindi phrase roughly translated as "we should get to know each other") was included in the opening credits of Ghost World and also used in the 2011 commercial The Date for Heineken. The song is sung by Bollywood music legend Mohammed Rafi. The main actor who danced in the film was Laxmi Chhaya. The psychedelic choreography was done by Herman Benjamin, who can also be seen singing the song onscreen.
Gumnaam became a box office hit. It was the 8th highest-grossing film in India in 1965, grossing ₹2.6 crore. This was equivalent to $5.46 million in 1965, and is equivalent to US$43 million or ₹275 crore in 2016.
