While searching for some more information, I came across this site that has all the text from the box set booklet. If anyone's interested. At first, I thought it was something new, but it seems it isn't...

Though it for example explicitly states that Why Aren't You Dead has been demoed for KTF (and states the reason why it's not been included), as well as that Miss 4th Of July is from the Grey Summer period (he even mentions it by name, does it stem from that?) Sorry if it's been posted/confirmed for those songs by now, I'm too lazy to read all the pages again right now
