Renowned ghazal singer Jagjit Singh continues to be critical in the Lilavati Hospital, where he was admitted and underwent surgery Friday, a hospital trustee said Saturday.

Further details of his condition were not revealed. "We have to respect the patient`s privacy," managing trustee Niket V. Mehta said.

The 71-year-old Singh is currently in the ICU after undergoing emergency surgery for brain haemorrhage Friday evening.

Singh and maestro Ghulam Ali were scheduled to perform at a concert in Shanmukhananda Hall in central Mumbai. The performance was cancelled.

Singh has been suffering from high blood pressure since the past few years.

Known as `Ghazal King` of India, Jagjit Singh, and his wife Chitra are considered the pioneers of modern ghazal singing in the country.
