Warning: only the refrain is in French. The rest seems to be in Norwegian.
Comment ça va? [How are you?]
comme ci, comme ça [So, so]
Tu ne comprends rien à l'amour [You don't understand nothing about love]
restez la nuit [Stay the night]
restez toujours. [Stay always]
Comme ci, comme ça = like this, like that = So, so.
