Alouette, gentille Alouette
Alouette je te plumerai
Alouette, gentille Alouette
Alouette je te plumerai
Je te plumerai la tête
Je te plumerai la tête
Et la tête, et la tête
Alouette, Alouette

If I remember my high school French:


Alouette, kind (nice, friendly) Alouette
Alouette, I'm going to pluck you
Repeat
I'm going to pluck the head
I'm going to pluck the head
And the head, and the head
Alouette....

As the song continues you change the body parts that are plucked. It is a kid's song.
