First, I'd keep the Discotheque video and the KMart thing - it took people off guard, That was good. Keep the ABC special, just lose Dennis Hopper as the host ("They're still wrting Sunday Bloody Sunday, maaan, they just call it Please, maaan" -- Your nitrious oxide is in your dressing room, Mr Hopper) And maybe not tie it all in to ABC as much.
Next, do not release Staring At The Sun as the next single. If you've got interviews with Edge and Larry saying they feel something is wrong with the song, don't release it. Go with 'Do You Feel Loved'. It's radio friendly and there's just something about it. Release it with a kick-ass looking video by Nigel Dick or someone out of the usual U2 video loop. Also, forget the 73 remixes, put some decent b-sides on that bitch. If the boys were trying to compete with the likes of Oasis (who were huge at the time) then compete with them on every level. Oasis consistently releases amazing b-sides. One-up them.
The tour -- Really go with the supermarket on tour vibe. Open the show with some kind of video screen display showing off what it can do and then have a female announcer: "The Popmart is now open!" Have the guys open with Playboy Mansion totally playing off the supermarket vibe. Save the Mofo/Boxing Ring entrance for the first encore and the Lemonball entrance for the final encore.
Next, release Gone as the third single. Maybe in a stripped down (new mix) version. And have a video that shows U2 can rock with the best of them. This song deserved better.
By this time, they probably could have figured out what was wrong with Staring At The Sun and then release it, or IGWSHA.
Finally, release anything but the Mexico show. It was a good show, but the Oakland show I saw was a million times better. AND I didn't have to hear Bono say "Mexico" 267 times. Release it with extra footage, maybe the ABC special and more behind the scenes, making of the album, stuff. Put it on DVD already and make us happy.
Not that I've taken the time to think about this over the last few years or so.
As Dennis Miler says, "Of course, that's just my opinion, I could be wrong."
