MUMBAI: Singer Sonu Nigam is still simmering over the punitive action taken by the directorate general of civil aviation (DGCA) against the crew of a Jet Airways flight which let him sing a few numbers on a chartered flight last week.

In a Facebook post, Sonu has put out a video of a Brussels Airlines flight that has crew and passengers taking off on a musical journey. "Some are still stuck of a fallacy that some rule has been broken," comments Sonu on his Facebook page. "They are deaf to the information that fashion shows, music launches, marriages have been performed in India itself..... Let not your jealousy take over your respect because as I always merely arguing without knowledge, doesn't suffice for intelligence. It will only make you look like an envious swine," says Sonu, taking a swipe at his detractors.

Here is the post that Sonu put up on his Facebook page:
