Nobody forgets, Platko,
No, nobody, nobody, nobody,
blond bear of Hungary.
Nor the sea,
That in front of you jumped without being able to defend himself.
Nor rain. Nor the wind, that were the one that roared the most.
Nor the sea, nor the wind, Platko,
blond Platko of blood,
guardameta in the dust lightning rod.
Not nobody, nobody, nobody.
blue and white T-shirts, on the air,
opposite, against you, flying and dragging you.
With alligator blood in your mouth,
Platko, distant Platko,
blond broken Platko,
tiger burning in the grass of another country.
You, key, Platko, you, broken key,
golden key fallen in front of the golden porch
