His passing away has left a vaccum which no one will ever be able to fill.
He sang over 25,000 which at that was a world record.Just recently, A.R. Rahman mentioned he is searching for someone like Rafisaab. Will he find him? That's a big question.
Yes, he was a versatile singer, but was also a gem of human being and a gentleman. Even the great Manna de said he was the greatest of male playback singers in Hindi Cinema. I have a collection of his movie songs and private Mir Ghalib Gazals so soulfully rendered.
Least I can say is, I still miss him. May God rest his soul in peace.
