This masterwork of short prose, which the author defines as a string of images and sounds, features two theoretical physicists as its protagonists: two Hungarian Prosperos, if you will. Cholnoky has calculated the exact moment in time when the world would end and after forty years of absence has returned to Hungary from the United States to spend the last hours of life on earth with his old mate from school, Miklós Szontág. During their conversation, the world expands endlessly, just like it seemed in their youths. The time lost seems to belong to another universe of almost ungraspable memories. The two friends walk down this happy and mysterious labyrinth with no end in sight, while the last 120 minutes of their lives trickle away. The memory of bells tolling in their hometown accompanies them, followed by the enigma of a breakup and of a merry song (hence the title). Their final mood is somewhat melancholic as if they were saying: “By God, we could have been happy after all…” All essential trifles of life, which question whether the end of the world will ever be absolute. We witness the battle of the Universe against the Black Hole of Nothing in this thought-provoking short story.
