[1] The song makes references to the 1972 Summit Series (particularly the famous game-winning goal of the series), hockey legend Bobby Orr, and the fitness test administered via the Canada Fitness Award Program.
The narrator appears to be a middle-aged individual, speaking to an unnamed spouse about the history of their relationship.
This relationship began on the last night of the Summit Series, and continued through a time-period partly contemporaneous with the remaining years of the Cold War.
The underlying theme of the recollections is that the couple's relationship has managed to survive for a significant number of years, unaffected by, and perhaps even serving as a defense against, external pressures.
The song was featured on the season 5 episode 19 of Corner Gas entitled "Final Countdown."
