It was very recent when Indian singer Sonu Nigam praised the 8-year-old Hadiya Hashmi for her amazing performance in Nescafe Basement. And now once again, the singer took to social media and shared a throwback picture along with a caption with Pakistani music maestro and ace singer Sajjad Ali, also reminisced about his pleasurable meeting with him. "Incidentally one of the most respected singers and musicians of all times, and my personal favourite Sajjad Ali bhai was there too with his son and it was so sweet of him to wait till I arrive so we may meet for the first time in our lives," he posted. "And then we chatted for an hour and a half. For people who don't know his Katna Nai is one of my family's most favourite songs and so was covered by my sister Teesha Nigam," the music composer added. "I wanted to go about it absolutely respectfully and thus I called Sajjad bhai to seek his permission for the same. It was very gracious of him to not just give us the permission for the same but not even charge for it! That's called true graciousness."
