Bollywood music composer and singer Aadesh Shrivastava, who was battling with cancer, passed away here on Saturday.

His cancer relapsed for the third time and he was in critical condition for over 40 days. Shrivastava breathed his last a day after he turned 49.

His brother-in-law and music composer Lalit Pandit, from the Jatin-Lalit duo, confirmed the news to IANS over a text message.

"Aadesh passed away at 12.30 am," the message read.

The singer, who earlier battled with cancer in 2010, was undergoing treatment in Kokilaben Dhirubhai Ambani Hospital here.

Shrivastava composed music for films like "Chalte Chalte", "Baabul", "Baghban", "Kabhi Khushi Kabhie Gham" and "Raajneeti".

He was married to actress and playback singer Vijayata Pandit. He is survived by his wife and two children.

Lalit had earlier told IANS that despite doctors trying their best to help Shrivastava overcome his illness, the treatment remained ineffective on him. Lalit had also noted that they need everyone's prayers.

As the news of his illness surfaced in the media, members of film fraternity like Lata Mangeshkar and A. R. Rahman expressed shock and hope for healthy recovery while others like Amitabh Bachchan and Shah Rukh Khan met him at the hospital.
