Answer:
Bill Barilko
"Bill Barilko disappeared that summer
He was on a fishing trip
The last goal he ever scored
Won the Leafs the cup
They didn't win another till nineteen sixty two
The year he was discovered"
The opening lyrics to "Fifty Mission Cap" outline the tragic and sudden disappearance of Bill Barilko, the Toronto Maple Leaf defenceman who scored the Stanley Cup winning goal on April 21, 1951 against Montreal Canadiens goaltender Gerry McNeil. It would be the final performance and goal scored during his five year NHL career. Less than a week later, on August 26, 1951, Bill Barilko and his dentist Henry Hudson went on a weekend fishing trip north of Cochrane, Ontario on a Fairchild 24 floatplane, but never returned. It was not until 1962 (ironically the year the Leafs won their next Stanley Cup) that the plane wreck was discovered and Barilko's body was laid to rest in his hometown of Timmins, Ontario.
