Really good translation I got off Youtube:

You're wearing trousers with a tag on the back
and a cap with the visor turned up,
parading around Tuleto
like a lady's man trying to be seen

You're acting all american,
american, american,
listen here: who's asking you to?

You want to be all trendy,
but if you drink "whisky and soda"
you always end up sick!

You're dancing rock and roll,
and playing baseball,
but where'd you get the money 
for the Camel cigarettes?
Mummy's handbag!

You're acting all american,
american, american,
but you're born in Italy, listen here: 
there's nothing you can do,
ok napoletano?!
You're acting all american,
american, american,

How can your loved one understand
if you're speaking half american?
When you're out loving uder the moon,
where do you get a phrase like "I love you"?

You're acting all american,
american, american,
but you're born in Italy, listen here: 
there's nothing you can do,
ok napoletano?!
You're acting all american,
american, american,
...whisky soda e rock and roll
