Queen - Seven Seas of Rhye - first Top of the Pops performance

This is a test encode of a project I've been working on for some time now. As most of you know the original recording of this show was deleted many years ago. Queen Productions probably managed to get a full colour copy, but most of the fans have only a black and white copy plus a couple of full colour snippets. I have tried to join all available videos together, but I'm not sure about the result. Please let me know what you think about merging colour and B&W footage, especially in the parts where you can see the colour version and the black & white version at the same time
