Yeah, the 11OTT single was recorded before the Boy sessions, so I imagine that had it been on the album, it would've been re-recorded just like they did with Twilight, Out Of Control, Stories For Boys, A Day Without Me, ATAP, and S&TT. I have no doubt it would have been improved and would have reflected more the quality of the live version, just like all the other re-recorded tracks did.
I suppose the reason 11OTT wasn't considered like all those other songs were, was because it had been the a-side to a very, very recent single. Just like how they didn't re-do Another Day. The only song they re-recorded for Boy that had actually been released already in 1980 was Twilight, and that was just as a b-side taken from an old and terrible demo. It obviously needed to be improved. Thank god they did; I don't think any other U2 song has had such a positive and dramatic turn-around in quality.
