This post begins with a huge warning. No one . . . let me repeat, ABSOLUTELY NO ONE . . . could be better than Screamin' Jay Hawkins. His "I Put a Spell on You" is worthy of the adjectives a true classic.

There is an other version from last year, showing the then 65 year old Brown, his face painted like an ur-Gene Simmons or an incompetent high school footballer's, looking like he is competing against Max Von Sydow and Peter O'Toole for the title of gauntest man in Europe, that I will not show here.
