I promise you they wouldn't skip it out for "morales".
I have to agree with this one.
Drinking isn't looked at the same way in many other countries.
The places that make the biggest deal and have the most rules about stuff like that have the most trouble. If they left it out, it's because of time or plot or whatever...
And the lyrics to that song...
It fit when it showed Syaoran and Sakura, and then switching to Fai and Kurogane fit so perfectly, and my mouth just hung open through that whole scene. I had to watch it three times before I could catch the animation, I was so amazed by the words and how they were reacting along with the lyrics.
This episode was just amazing, and so telling.
