Amitabh Bachchan's iconic song 'Khaike paan banaras wala' was originally written for Dev Anand's film

Who knew that the iconic song `Khaike Paan Banaras Wala` was not supposed to be a part of Amitabh Bachchan starrer `Don`.

In a tweet on Wednesday, Big B went down the memory lane and confirmed that the song was shot after `Don` was completed.

Big B tweeted, "T 2849 - An after thought, that became THE thought .. song `khaike paan banaras wala` was done after film DON was completed ..(sic)"

The song was actually supposed to be a part of the Dev Anand's film 'Benarasi Babu' but the makers decided to include it in 'Don' post interval to break the monotony of the action sequences. It was shot after filming was complete and was added after the intermission.
