It is material cut from Rattle and Hum and it is one of the Tempe 87 shows. I "think" it is the 12-20-87 Tempe show but I'am not for sure on that as there is no distinct audio differences between the performances of that song from 12-19 to 12-20. The camera angles and overall footage appear to fit more with 12-20 though over 12-19. But, again, I'am guessing as I have never really looked at or compared it that closely. The time bar is an editing feature that appears on all the raw footage (take a look at the Rattle and Hum outtake DVD's and you will see it there also). Its so they can edit different camera angles and keep it all in sync. Usually the bar is taken off but they apparantly just threw the raw footage for the Best Of video so the time bar is left on there.
