Dissention - Leave NMB out of this!
On the 'I Know I'm Not Wrong ' front, I agree with ChiliD that each version will be of very different stages in the song's evolution. You will note that there's no demo or outtake for 'not That Funny'. As we all know, these two songs are extremely similar in different ways (both in C, both with similar chord progression and rhythm, they even share a verse). My guess is that the first 'I Know I'm Not Wrong' track is in fact an embryonic 'seed' song which diverged from that point into the two different songs. So I wager that the second one will be more like 'Not That Funny' and the last will be more like 'I Know I'm Not Wrong'.
Just a guess though. As someone has justifably said, there could have been some minor errors in the transcription of this track listing.
