It is 'foreign muck', I know, and I also have no idea what the song is about or who the guy is, but, who cares? Here is a flashmob in Budapest Nygati station, complete with loco 431221 (*) making a star apperance along with loco 480020 and EMU 804404 (I think).
* - 431221. One of a class of hundreds from the Soviet era, these diminutive, almost minnionesque in appearance locos are probably the most common locos in Hungary. I like them.
The intro is quite long, I'll admit, but you get to see trains and stuff!!:
