Massiel: “El Amor”.

El amor te hace burla, se ríe de ti,
mientras tu sigues quieto, sin saber que decir,
y deseas seguirle y decirle que no,
que se quede, que vuelva, que comete un error.

This is the quite uneasing soundtrack from the not less uneasing movie “Ventajas de viajar en tren”. In 1968 Massiel won the Eurovision Song Contest – with a less ambiguously, a cheerful song of course but also with an interesting story.
