the final versions of those songs end up at 14:30 and 14:50, not exactly the same the way they were originally. i guess they decided the synchronicity wasn't as important as making the songs the length they "should" be? (which is a little weird, especially given the careful synchronicity in Bath/LYBM).
and, i don't know if i'm right about this, but is the extra time on "The Antique" due to the addition of that tremulous beginning part? if so, i would say GOOD SHOW, because it's an awesome way to open the song.
