Thank you, Nacho, for the suggestions. Sorry for the late reply. I was away for a long time. The lyrics were the same as everywhere else on the net and they were partially wrong. Only now after careful listening I corrected them. I wonder why I didn't do that earlier.

"Te ha enseñado" was of course grammatically wrong. Nevertheless, when I was reading I saw what I wanted to see. I translated it now a little different than you suggested. In correct English it should be "than I". "Me", even if that's the form that most native speakers use in this context, is not correct from the grammatical point of view and I care not to use it this way.

I have corrected "tanto" -> "aquel", "a dónde" -> "adónde" (both forms are acceptable, but RAE recommends the second one) and transcribed the missing part that is now in place of this two verses that Julio doesn't sing:

Más que yo nadie, mi amor
Busco tu amor con tanto amor

In the second stanza the missing punctuation can be misleading. The sentence the way Julio sings it - with punctuation - is: "Un atardecer llegaste a mí,
como primavera, a mi jardín" - not "en mi jardín".
