The Spanish anthem of Marquina, a monarchical anthem during the reign of Alfonso XIII of Spain.
I think it would be nice if Philip VI restore this anthem:
Glory, glory, crown of the Fatherland
sovereign light
which in your standard is gold.
Life, life, future of the Fatherland,
in your eyes it is
an open heart
Purple and gold: immortal flag;
in your colors, together, flesh and soul are.
Purple and gold: to want and to achieve;
You are, flag, the sign of human effort.
Glory, glory, crown of the Fatherland
sovereign light
which in your standard is gold.
Purple and gold: immortal flag;
in your colors, together, flesh and soul are.
