That's a great song, period! If I may make a suggestion anyway... I would elevate every "There's no Magic in Mexico" part, by singing it in harmony, and also inserting a quick lick with a nylon string guitar right after. Make it sound more mexican.

I began in 1970 with a 7 piece dance band. I had other bands, but my most successful one was "The four Windows", a 4 piece guitar band. Many concerts, TV shows, Record contract with EMI and a guitar hit in 1982 in Europe with my "Lonely Seagull".
