Uncover the magic behind Antonio Vivaldi’s compositions, understand what was going on in Napoleon’s brain when he thought invading Russia was a good idea, make a Top 10 List of things needed to be successful with Walt Disney, listen to a bald, fat, drunk, old British guy talk about perseverance through the darkest times while smoking a massive cigar.
