Pro hockey history enthusiast/author Steve Currier (Episode 37; "The California Golden Seals: A Tale of White Skates, Red Ink, and One of the NHL's Most Outlandish Teams") returns to the show after a five-year absence - this time to accompany us deep down the rabbit hole of one of the National Hockey League's most overlooked adventures of the 1970s.   In his new book "When the NHL Invaded Japan: The Washington Capitals, the Kansas City Scouts and the Coca-Cola Bottlers' Cup", Currier recounts the story behind the NHL's long-forgotten, but historically relevant 1976 promotional exhibition series (colloquially known as the "NHL Japan Series") between the league's two most lamentable teams that year - the sophomore-twin Washington Capitals (11W-59L-10T) and Kansas City Scouts (12-56-12) - and their curious mission to introduce professional hockey to the Land of the Rising Sun.
