The woman leaning against the side of the train, above the VH1 logo...is that not the extra space which they put in the Picadilly Line trains to deal with the large amount of luggage for passengers to/from Heathrow?
the other one i thought it could be was the northern line, but i think the map up there is a piccadilly line map. and they don't have much space in the aisles either.

If it is not a especially refurbished train, then it is most definitely a Northern line train, about 3 minutes into the video there is quite a good close up shot of the seat upholstery. The old Piccadilly line upholstery and the Northern line are the same pattern just different colours, easy to confuse. The space by the doors, is where the two seats fold up no one is sitting down!
To answer the question, the video was filmed on a Jubilee line train between Charing Cross and West Hampstead and back. There is a page on the LU intranet that details any filming that has taken place, and Hung Up is mentioned here.
