I would love to watch the first one (I can see that it's the Rap God interpretation), but hey.. Germany, GEMA vs. Google and that's it.
That said, the second link worked and looked awesome. Very interesting to see how people are mixing a performance with the translation, although I cannot judge the latter myself.
So, same person, signing 'Black and yellow'. Before the performance starts, the host asks if the lyrics will be 'toned down' for the signers. Nooo. That's the fun. And at 1:50 (the first time our female protagonist starts signing parts of the song) her hands are blurred out....
