I don't know a lot about Juan Gabriel either but this is definitely not "Hasta que te Conocí" so it must be his new FS. Glad he can get to practice it with public!
I was trying really hard to hear the words to see it it was the new FS, but I couldn't tell if there was an echo or the sound was muffled. Couldn't understand a word! ...I heard he is from Zapopan. I've been there!
