Once all the fluff and butthurt dies down, y'all got a great anthem. It's singable for people that ain't operatic tenors, it's inspiriational, it ain't drippy with Love of Dear Old Whatever. Better'n Star-Spangled Banner. Better'n Advance Australia Fair. Better'n Soldier's Song. Not as blatantly butt-kissing as God Save the King (Queen). Easily translatable to account for French.
Good, serviceable anthem. Best to keep it.
You need to make your's gender neutral as well by picking a more androgynous name as it's opening word than "Jose".
