Letra de Cosi-Cosa - Max Raabe

There's an old Italian phrase.
It's an old Italian craze.
Ev'ry little bambina
learns it the very first day.
Ev'ry sweet Signorina
says it the very same way.
These funny little words
don't really mean a thing.
It's just a phrase, that nowadays
Italians love to sing.

Cosi-Cosa!
It's a wonderful word tra-la-la-la.
When anyone asks you how you are,
It's proper to say Cosi-Cosa.

If a lady should ask you if you care,
You don't have to start a love affair,
Say Cosi-Cosa!
