the guy hosting the original post's link on youtube is one of my best friends. he's Irish... now all married up and living here. but we've seen U2 several times together- twice in Ireland... once at Slane Castle and once at Croke Park (which he grew up within walking distance of, and he also has video of on youtube.)
and he also makes an appearance here, it's my favorite live concert footage (because I shot it... back when a digital camera couldn't zoom once you started video. it's sliced together, and the audio is from a better source. I still watch it all the time: it makes me happy. at the end, another friend even throws up the horns): Radiohead's "Creep"
