Man plays Beatles song on his guitar during brain surgery

Anthony Kulkamp Dias, 33, discovered he had a brain tumor 15 days after his son was born.

He realized something was wrong when he began stammering and forgetting things. He couldn’t remember the simplest of details, including the make of his car, he said.

Last week, he underwent surgery to remove the tumor. Doctors kept him conscious during the surgery so they could monitor the areas of the brain relating to speech and motor coordination. Keeping brain surgery patients awake allows physicians to speak to them during the operation and chart their responses.

Instead of reading or telling stories during the procedure, Dias did what he does best. A 20-year guitar player, Dias serenaded his doctors while holding a guitar on his stomach.

In addition to his emotional rendition of “Yesterday” by The Beatles, he also played a song called “Emanuel,” which he wrote for his son.

Dias says that 90 percent of the tumor was removed during the surgery, which he says was pain-free. He said he hopes the video of his performance will be inspiring.
