Can someone explain Badly Drawn Boy's guitar rig?

NTI, your show is mentioned on setlist.fm🕸 but doesn't have an, errr, setlist. Maybe this show🕸 from around the same time can offer some clues?

That’s actually the next time he was in town! Apparently by 2004 he was surly and complaining that DC only had one place to play (it has more).

My show was from November 4, 2000 – and I actually tried what you suggested. The only thing I can figure was that it might have been a rearranged Disillusion? So weird.
