Lyrics:

When in Spain, for reasons I don't explain
I remain enjoying a brew
Don't deplore my fondness for Fundador
You know how a Fundador can lead to a few
And baby, when in Rome, I do as the Romans do
If per chance I'm saying farewell to France
And romance drops in from the blue
Cher amour, I beg of you, please endure
My taking a brief detour with somebody new
It's just that when in Rome, I do as the Romans do
And though from Italy I lie to you prettily
Why think of me bitterly, you know that I'm true
'Cept now and then in Rome, I get that old yen in Rome
And naturally when in Rome, I do as the Romans do

If I write happily, 'Best wishes from Napoli'
Don't cable me snappily to tell me we're through
'Cause once again in Rome, in somebody's den in Rome
Well pussycat, when in Rome, I do as the Romans
Disregard the signs and the omens
When in Rome, I do as the Romans do
