This is the musical moment a man serenades an operating theatre on a keyboard during an operation on his brain.
The 28-year-old patient, who has not been named, was having the tumour removed during a delicate procedure in Bhopal, in the Indian state of Madhya Pradesh.
But instead of knocking him out with a general anaesthetic, surgeons drilled into his skull to remove the tumour.
Then he was asked to perform a series of tasks so surgeons could tell if his brain was being damaged by the op.
Hospital video footage of the op shows the patient wide awake during the craniotomy with the keyboard on his torso as he plays a tune.
Behind a screen around his skull, surgeons work on locating and removing the life-threatening growth.
The patient also read from a newspaper and recited a Hindu hymn called Hanuman Chalisa while playing the cymbals, as can be seen in the footage.
Medics at the AIIMS Bhopal hospital told local media that the keyboard would warn them of any potential damage to the patient’s motor functions if could no longer play.
Dr Sumit Raj, a professor of neurosurgery involved in the op, declared it a complete success.
He said: “He has shown no signs of adverse effects from the procedure and has full control of his motor functions.”
