The Free Mexican Air Force by Peter Rowan

In the Morelos mountains campesinos are planting their fieldsWhere the ghost of Zapata flies a ship that can still outrun the windThere, free in the sky, and clear out of sight...It's the Free Alien Air Force, flying tonight!
In the city of angels, a Man-In-Black's cooling his heelsJust waiting for orders from Uncle Sam's spooks in the fieldBut it's much farther south where those little green men take to flightAnd then the, Mexican Air Force,Scrambles up on an inter-cept course,But the Free Alien Air Force is flying too high!
Flying so hi-i-igh...i-yi-yi-yi-yi!
Old Uncle Sam's cover-up-lies hide these alien trendsThey might kill you if they think you've got alien friendsBut they're fools who make rules out of fear of what flies in the nightBecause the Free Alien Air Force is flying tonight!
Uncle Sam in his paranoid fear shut-off the mountains that sur-roundThe Area called Fifty-One on Dreamland's dry Groom Lake groundNow the only civilians who dare fly over that siteCome from the Free Alien Air ForceUncle Sam's jets, scramble up, of courseBut the Free Alien Air Force is flying too high!
Flying so hi-i-igh...i-yi-yi-yi-yi!
(instrumental)

Is not propaganda destroying the minds of the young?The cover-up continued for power and greed in all forms!May the lies of the evil soon fall to the truth and the light!As the Free Alien Air Force flies freely tonight
Not even the President knows the full truth of what's going onAnd the media's co-opted, bought-out, and they're singing their songThey think none can stop them, their arrogance too great to fightThen their High-Tech Secret Air Force,Scrambles up on an inter-cept course,But the Free Alien Air Force is flying too high!
Flying so hi-i-igh...i-yi-yi-yi-yi!
Some ships come from Altair while others are coming from RigelThe Men-In-Black who watch them all use the alias "Nigel"It's all a chess game -- Earth's black and they're white,And the Free Alien Air Force just captured Earth's knight!
High in the skies they're discussing their plans for their landingTo welcome Earth to the Galactic Village in good standingAnd freedom for us is the prison for the rulers of might!That's why the Free Alien Air Force is flying tonight!
The Free Alien Air Force,With Element One-Fifteen fuel-source,Yes, the Free Alien Air Force, is flying tonight!
