Christopher Lee was a total badass long before he played Saruman, Dooku, or Dracula:
He witnessed the last execution via guillotine in France. He fought in the Winter War in Finland in 1939. He was in the SAS in North Africa during the War. He was cousin to Ian Flemming, who tried (and failed) to get him cast as Dr. No (he had to wait until Man With The Golden Gun to play a Bond villain).
But this post is about his musical career which is nothing short of amazing. He had classical voice lessons to develop a basso profondo operatic capability. He’s continued his recording career, most recently with the Symphonic Metal band Rhapsody Of Fire.
