"Imagine" memorial to John Lennon at Strawberry Fields in Central Park.

In the 45 years since the release of John Lennon’s 'Imagine' as a single in October 1975, the world has undergone enormous changes, one of the most significant of which was the Fall of the Berlin Wall in November 1989. 

This paved the way for German reunification in October 1990 and, in turn, triggered the dissolution of the Soviet Union in December 1991.
