I figured it did. They played it a lot for the IaW tour, didn't they? And it's on the live releases that followed FII and SFAM. So I figured they played it as their "epic". It was the only epic they had, after all. But maybe I'm wrong; I didn't actually check the setlists.
They only played it twice on the I&W tour (as explicitly stated in Lifting Shadows). They also played it twice at their some instrumental only gigs in 1990 when they were between singers (I used to have a boot of one of those shows, but sadly I have lost it
), and they would play instrumental segments of it when Charlie was in the band. Those are the only times the song was played before the release of the EP.
Post-release, ACOS got it's own mini-tour, where the song was played every night in full. It was also played in segments on the FII tour, and as a whole on the tours for both SFAM and TOT. Since the ToT tour, I do not believe it has been played at all.
As for whether or not we will here the song again, I believe we will, with or without Portnoy. As has been pointed out, while the lyrics may be MP, the song was written by the band as a whole, and it is as much their song as it is his. In fact, I would think that any MP songs they have been playing for years and years would be on the table for a setlist, since overtime I'm certain the band has come to think of them as simply "Our songs" rather then "Mike's songs". The only MP songs I can see them not wanting to play without him are The Shattered Fortress and The Best of Times because those were never played when he was in the band and I doubt they would want to debut them without him. But other then those two, I think any Portnoy songs should be considered free game for concerts.
It was played for the Live Scenes show, but I don't think it was played very much that year other than that show.
Actually, according to MP's tourography, it was played quite a bit on the SFAM tour............
