What does that have to do with the setlist that includes SA? What kind of environment made them play SA? What made it so special that they decided to play that song for the first time since 1999? Did you even check that setlist? And, finally, why are you firgetting the part where the setlist that you linked was going to be used for a live dvd release?
"Hey everyone, here's a song we haven't played for 23 years. It's from an EP released before half of you were born. Nobody currently on stage was even in the band when this song came out. We also thought so much of it that we didn't include it on our 2004 live DVD, when it would have been far more relevant. Anyway we've randomly decided we really like this one now for absolutely no logical reason, so even though basically nobody here will know what this one is, and even if you do like it you'll not be able to buy a studio version with me and Bjorn on it, here's Stand Ablaze"
"Hey everyone, here's a song we haven't played EVER! It's from our most commercially successful record, yet somehow we never found it worthy to play live, not even during our In Our Room tour, where we played Dawn of a New Day, but not this one! Anyway, we've randomly decided we really like this one now for absolutely no logical rea..." You get the idea about Metaphor.
Now let me present you with a baffling alternative: they wanted to do something special, something unexpected - WHICH THEY HAD BEEN TRADITIONALLY DOING IN THIS VERY FUCKING VENUE. Would you have guessed they are going to perform Metaphor? No, you wouldn't have. That song should have been played ages ago, should have been a contender for a staple slow song, but at the very, very, VERY least it should have been played during one of their R2R tours. Yet they did not even fucking play it when they started to play Come Clarity again and when they debuted Dawn of the New Day. Metaphor is basically a song destined for greatness which failed two
"now or never" scenarios to be included into a tour, yet it was played in Borgholm.
Somehow you try to argue that playing a song which they haven't played in 20+ years, but at least was a staple for a short while is much more suspicious than busting out Metaphor there and then... You see what you want to see. And no, I am not saying that you can not possibly be right about SA, but first of all, your argument is weak, because Borgholm is special and while Anders and Björn did not have much to do with the studio version, at least they did tour with that song for a while, which you just keep casually ignoring as an irrelevant fact. Moreover, the whole idea of being aftraid of THE stealing the fans which IF doesn't even have - nor do I think they want that much - nowadays is just interesting to say the least. If you are someone who goes to IF live events then you don't do it for songs like BS or Pinball Map. Even if you are an old-school fan, you have to concede that they may not play jackshit from that time, and if they do, that is just a nice extra. You can't sway the kind of fans you could possibly sway away from IF shows with an act like THE, because those fans do not go to IF shows anymore to begin with.
