Loved watching that.  Getting video from a HOB is like sneaking a cookie from the jar on the very top shelf  at grandma's house - just more of a treat !
HOBs do take their No Cameras policy seriously for certain and seems the artist has no say !   Was at one last year where they literally checked jacket pockets and purses - if they found a camera they kept it and gave the person a checkroom ticket to get it after the show - and charged a fee !   Know of one quick-witted  gal who got some video with her "bra-cam" - she was close to the stage and the angle was a little odd at times but hey - necessity is the mother of invention after all . .  :-)   
Apparently some HOBs have even put in ceilings that block cell phone signals - whether it was the intent or not - it does prevent people from  sharing a concert with a friend.
