Anders once said he doesn't even know the correct Stand Ablaze lyrics. I believe it was in an interview... He was explaining why they don't play certain old songs live anymore. One reason was some of the songs have 3 or more guitar tracks and therefore they don't sound as good live as they should. And for Stand Ablaze another reason was given: Anders said no-one, included himself, knows the correct lyrics. (To my understanding, Henke Forss wasn't completely satisfied with his lyrical work for Subterranean and therefore didn't want his lyrics in the booklet)
The S.A. lyrics at DarkLyrics.com seem accurate to me though. Actually I once copy-pasted the link to In Flames's guestbook and wrote something like "now you know the lyrics and the music will be fine with just two guitars, please play it" but as we can see, that wasn't of much help.
