Hate to disappoint you all, but keyboards, Arrangers & Organs are pretty common on German TV shows, (As well as live) so it is of no great surprise to see the T4 on there. (This is the reason that Germany is the largest Western market for Keyboards, Arrangers & Organs)
NOTE: You will find plenty others on YouTube
You will also find that most manufactures make custom versions for the German Market.
