Man Plays Beatles' 'Yesterday' on Guitar During Brain Surgery

The Beatles' iconic ballad "Yesterday" is one of most covered songs in music history – but even Paul McCartney would tip his hat to Anthony Kulkamp Dias, the 33-year-old Brazilian bank worker who strummed out the Help! anthem while undergoing a brain-tumor–removal surgery. "I played six songs at certain times," Dias told Brazilian news site G1 (via Telegraph). Dias, a professional musician for two decades, performed an array of material, including a song ("Emanuel") that he wrote for his newborn son.
