Bruce is way better on Live/Dead than on LAD (or Maiden England...) He's fucking awesome on Rock in Rio, but I prefer the sound of Live/Dead. RiR also suffers from the cut-and-pasting of the vocals where in reality Bruce let the audience sing - really a shame, and it's Steve's fault. My fave is En Vivo.
I also can't watch the video of RiR, which is just shit, sorry. Which brings me back to the feud between Steve and Bruce, because as far as I understand Steve is responsible for the editing of that video, and I think the cuts are so crazy fast in order to have an excuse for not showing Bruce. I guess Steve needed longer to come to his senses and let go of some ego crap - which you can also see in the reunion-interview Talisman posted, where he still fires against Bruce. As soon Bruce was back with Maiden, he was pretty loyal and professional and chose other targets to get the headlines (Metallica, Ozzy). Which again supports my theory that Bruce can be very "rational" in losing his temper.
