With immigration such a big issue right now I've been trying to think of an appropriate song lyric. Led Zeppelin's "Immigrant Song" has the right title, but the lyrics have more relevance to Nordic mythology than contemporary discussion. Genesis' "Illegal Alien," on the other hand, would seem to fit the bill (and it has a funny video). Here's a taste of the lyrics:

Down at the office had to fill out the forms
A pink one, a red one, the colours you choose,
Up to the counter to see what they think
They said "it doesn't count man, it ain't written in ink"
I don't trust anybody, least not around here, 'cos
It's no fun being an illegal alien . . .

Consideration for your fellow man
Would not hurt anybody, it sure fits in with my plan
Over the border, there lies the promised land
Where everything comes easy, you just hold out your hand

Are there other immigration-relevant songs I should have considered?
