The Doctor Who News Page reports that ONLY the Region 2 version will have the Beatles clip. All non-Europe versions -- which means Region 1 and Region 4 (I've never actually heard of anything ever being released in Region 3*) -- are being edited to remove the scene.

The news page is a bit ambiguous as to whether the entire scene might actually be cut (as in the complete time visualizer sequence).
This probably explains why, as best I can tell, no Region 1/4 release date for The Chase has been announced yet. (No release date's been announced for Space Museum either, which probably also suggests that we'll be getting the same box set with both stories, unlike the Peladon Tales set which for some reason is being released separately in Region 1 rather than in the box set the UK and I think Region 4 is getting).
I really am starting to hate lawyers and penny pinchers. They destroy so many good times it's not even funny. And I know for a fact the artists themselves rarely support this because I've heard, for example, Adam West bemoaning the fact they can't get their collective acts together to get Batman on DVD.
Of course the laugh is on them because that scene will be visible around the world via things like YouTube anyway.
The only person who might be happy is William "Mr. Jitterbug" Russell!
I'm just happy the Beatles were such huge fans of The Prisoner that they signed over All You Need is Love in such a way that the use of that song in that show's finale episode has never been an issue.

* Region 3 is places like South Korea, though Japan is in Region 2 apparently. There's also a Region 5 which is much of Africa and the former USSR. Region 6 is China. Do these areas even get (official) Doctor Who DVD releases?
