I gotta go along with Jim on this one. Why are some people in hysterics about a Spanish version of the Star-Spangled Banner? I would think it a point of pride to have your national anthem recorded in other languages. Why would anyone feel threatened by that? Oh that’s right, paranoid xenophobic wingnuts, that’s who.
Of course I remember when certain narrow minds were upset when Jimi Hendrix did his famous and beautifully played electric guitar version of the SSB at Woodstock. Ironically, these people were offended by it being played on the electric guitar and, for the most part, they missed the embedded musical political commentary when he recreated the sounds of falling bombs and explosions in the middle of that rendition (a nod to the ongoing Vietnam War).
So get over it people. Stop treating things like anthems and flags as divine and more sacred than what they stand for.
