LOL, great show, +rep to CrashToOverride for sharing it! :-)
I've also noticed they don't really seem to even CARE what goes on. Then again, it's the NYC subway, they've probably seen quite a few weirdos and have become largely immune as a consequence.
Nevertheless, the RickRoll LIVES!!! You just can't kill a meme this "popular". And now in real life, too!

Funny thing is..they are actually quite good and semi-famous singers. Sang it better than mister Astley himself in my opinion xD

Indeed... It seems NYC subway passengers also don't appreciate talented singers (at least outside of the TV and radio).

I think they are just happy they are not naked.

I know, I told you that. :P
It's the Blu-ray and DVD releases. And supposedly there is already a version available with the proper subtitles (listed as English - Theatrical).

I'll have to look into it now. Apparently they did good jobs on the disc, good picture quality and sound. Heard there is even a book that is really good too. Even scarier than the movie the reviews say.

I wonder if being in tune with the train's brakes was part of the plan.

Yeah that was kinda funny, but HUGE balls? Eh I dunno, imo it doesn't seem like something mind blowingly ballsy.If you're a performer you should be used to being in front of possibly unfriendly crowds. I don't know if I have ever seen it happen on the train itself , but is it really any more ballsy than singing/playing music at the subway station or even just a street corner? I've seen that all the time.
Maybe it's a big city thing. I lived in Chicago and if I saw something like this happen I wouldn't be totally surprised either.
