This is going to be hard to hear, but:

Bryan Adams released "Summer of '69" in 1985. A similar nostalgia-based song released now would be harkening back to the distant and bygone year of 2010.

@jsr Marty McFly’s 1955 would be 1996.

Gone with the Wind's 1865 would be 1952.

Maybe more to the point The Birth of a Nation's 1865 would be 1976.
