First off, since I'm new here, I apologize if this has already been covered/answered. I tried looking back at older threads to see if it came up and didn't find anything obvious.
Lately, I've been watching a ton of Alphaville live videos on YouTube, just for fun. In a handful of recent ones, I've noticed the keyboard player is someone other than Carsten. Here's an example (not great since it's shot from a balcony, but notable because it's obviously a recent show and was just posted to YouTube today):

Bald guy. Same keyboard setup as Carsten, and seems to know the songs as well as anyone else. Who is it? Someone who travels with the band as a "stand in" of sorts? Just curious.
Thanks!
