“Yesterday” by The Beatles remains one of the most covered songs of all-time. Everyone who’s anyone has played it: Frank Sinatra, Boyz II Men, and now, a 33-year-old patient having brain surgery. He was kept awake during the procedure, and according to Boing Boing, after playing a “song he composed for his son, born a few months ago,” the man started singing about the shadows hanging over him, which in this case, were doctors POKING AT HIS BRAIN.
