The movie is DESPERADO (...read the credits....they are interesting ).
I do likes me some cheezy Mexican Fare and this movie Just Rocks!!
This song played by LOS LOBOS and Sung by ANTONIO BANDERAS is one of my all time faves even tho I don't speak Spanish. The name of the song is Cancione de el Mariachi (or Something sorta like that).
The guitar in this song for some reason just speaks to me, I can't say it is technically or even emotionally super exceptional it just Speaks to me... go figure.
