If you're trying to upload the video of 'Seven Seas of Rhye', just forget about it now...it's official, and is not allowed to be shared on here. Sorry to burst your bubble!!
If this is the one where you find the same video clip in black and white and one in colour that suffers from bad generation loss then I think you'll find that this is from the Dutch show called Top Pop or something like that and not Top Of The Pops. Rien had it on his site link a while ago
