The Mask of Zorro (1998)

Revealing mistake: In the scene where Captain Love and Antonio Banderas (as Zorro) meet in the hallway of the hacienda, two guards rush down the hallway and drop their rifles and swords. Zorro asks them to bend over and then proceed to kick/nudge them out the window. If you watch carefully, you'll notice that the guard on the right (furthest from Zorro) reacts to the kick too early. (01:33:30)

[Alejandro draws his sword.]
Don Diego de la Vega: Do you know how to use that thing?
Alejandro: Yes. The pointy end goes into the other man.

Trivia: Antonio Banderas was the first authentic Spanish actor (he was born in Spain) who played the Zorro character. All of the previous actors in old movies or TV series only had the Spanish appearance or ancestry.

Question: Who sang the closing song and what are the lyrics?
