Exactly.

It’s surprising how little video there is of Vangelis at work or in performance, especially for someone of his fame.

I’m always amazed at how Vangelis improvised completely arranged works throughout his career, regardless of the sophistication of his equipment.

There are lots of clips where he seems to be in this room with similar length of hair/beard that I’m referencing. So it is an early 80s maybe mid-80s piece of footage. Perhaps multiple people brought a videocamera in to capture the setup around that time. Either that or he moved some of the gear to another place and arranged it the same way. Perhaps another friend or promotion or studio person captured a session from which this is taken, or it is a clip from the same footage, so that was my guess.

This is an unknown video, you are probably recalling the Nemo Studios’ videos from TV, a profile on Vangelis called “Man and His Music”, they were two episodes broadcast on TV in the 80s, and you can easily find them on YouTube
