Yang Qiyu, you are the best friend in the world. I want to go with you.

A group of women shouted "I love you, you can't be with me without you". Obviously, men prefer the idea of "I'll go with you", so they left together (without luggage-).

The total length of that song is about 1 minute and 40 seconds, which is probably a little song specially written for sncf advertisement.
