WWE must have been sloppy while in the UK, Smackdown has leaked onto Youtube.
There's also this, someone got a hold of a dark match before Main Event between Sami Zayn and Adrian Neville. I guess they were filming it to check the cameras were set up properly or something, and someone nabbed a copy somehow.

It's pretty excellent for such a short match without any ringside cameras, commentary or crowd mics. Than again, they're two of the best guys in the company, so I wouldn't expect anything less.
