Quoting from the interview:
“Dhan te nan was not designed specially for Kaminey. I had first used it in a telefilm called Dhan Te Nan. I had used that catchphrase and the tune in that telefilm.
Dhan te nan is a phrase that belongs to our film and music culture. For us Indians cinema is the biggest cultural entity. We often borrow illustrations and speech patterns from our films. Dhan te nan is used during bedtime stories for dramatic effect.
Whenever I used to tell mey son Aasman stories I’d go ‘Dhan te nan’ to create drama. This phrase remained with me.”
