Quiero Saber 

Quiero saber
Que lo me importa de ti
Y conocer
Un nuevo amor
Y tu forma de ser
No llegue a comprender
Y tus ojos ya llorando un dia
Para mi
da-do (etc.)
Corre cada noche voy pensando
Como pienso en ti
Corre cada noche voy pensando
Como pienso en ti 
El amor que sera
Recordando el ayer

(translation to english)
(I Want To Know)

I want to know
What matters to me about you
And get acquainted with
A new love
And your way of being
I never came to understand
And your eyes crying one day
For me
da-do (etc.)
It occurs that every night I go thinking
How I think of you
It occurs that every night I go thinking
How I think of you 
The love that will be
Remembering yesterday
