It's a beautiful song. Should I ask for more?
I'm wondering about its composition.
Was it based on a death-journey from a myth? An exile's lament?
Maybe it just uses the symbolism.
I could make a few guesses of my own but I'm wondering about the actual intention of the author. The information on the net is swamped by tourist destinations, and such, using the name -- and by singers who've recorded the song - which is just about every singer of Mexican songs.

It's not in the DT so here it is:

La Barca de Oro

by Abundio Martinez (I think)

Yo ya me voy al puerto donde se halla
La Barca de Oro que debe conducirme
Yo ya me voy; solo vengo a despedirme,
Adios, mujer, adios, para siempre adios

No volveran tus ojos a mirarme,
Ni tus oidos escucharan mi canto
Voy a aumentar los mares con mi llanto,
Adios, mujer, adios, para siempre adios.

It's about leaving - alone - in a golden boat - never to return. He says goodbye to his woman and says he will increase the depth of the ocean with his tears.

That's it. It's brief and so, so sad. It's what True-love calls achingly beautiful. If that's all I get then it's OK. But I'm wondering about this old friend of a song.
Cheers, Joy
