Pakistani legend and Ghazal maestro Mehdi Hassan passed away Yesterday due to multiple organ failure. He was 84.

The maestro had been struggling with this life for over a decade now and was undergoing various treatments for lung, chest and urinary tract ailments in several different hospitals in Pakistan.

The death of Mehdi Hassan, who was very popular in India, came as a blow to Bollywood and many of his fans.

Veteran Singer Lata Mangeshkar, who did a rare collaboration with him for an album song, said that Hassan Saab was an outstanding singer.

“It is a very sad news. I am really upset ever since I heard this news. Not only me, the entire world loved his songs. There is no doubt about it that he was an outstanding singer,” she said to IANS.

“I have shared a very good relationship with him. I really respect him a lot and even he used to respect me a lot. I have met him just two to three times, he was a wonderful human being,” she added.

Not just Lata Mangeshkar but many from music industry have been mourning the loss of Hassan Saab, who is remembered for his timeless ghazal ‘Patta patta, boota boota’.

Legendary singer Ghulam Ali said that he was saddened by this news.

“I came to Mumbai a few days ago. But now, after hearing the news, I feel like going back. I feel bad thinking of his last days of illness,” he said.

“We used to sit together for nights. We have travelled together, performed together. There was lot of love between us. He stayed at Karachi, I stay at Lahore. I used to go once in a while to meet him. He was a big star of the music world. He will remain alive in people's hearts,” he said.

“He used to tell me that he liked my singing, and that he wanted to teach me. We performed together in 18 concerts. I feel very upset by his demise. It is very difficult to replace him. He had God in his voice,” he added.

Singer Hariharan, who shared a close bond with the maestro, said that losing Mehdi Hassan was a personal loss.

“It is a personal loss. He was a guru figure to me. He made me understand the marriage between words and tune. His contribution is unprecedented,” he said.

Others took to Twitter to let their thoughts be known.
