I too think it's a beautiful little video, telling a lot without words. Bart asks, what he's actually saying in the taxi on his way to his last performance. It's not much of significans, but here's a summary:
The taxidriver recognises him and asks how old he is, since he has to retire. Hübbe answers, that he is forty and then makes a Danish joke with three f's: forty, fat and finished. Then he changes the joke and makes up three other f-words, this time with a positive value, something like: forty, fastgoing and fiery.
In the theatre he says, fiddling with the waterbottle, that one's biggest worry is to get safe through the solos, meaning not getting injured. Then he asks for some time on his own to be able to concentrate.
Later we see him dressing, and he's annoyed because he's sweating a lot, from nerves I guess, his clothes are all wet. In the meantime you see people fill up the theatre (including myself and my husband!

).
I think, that's all that needs to be translated. If some of you want more translations, don't hesitate to ask.
