It's one of these song titles that may be a masterpiece, but may be yet another blues track just as well. Considering it wasn't even a bonus track, I have doubts, but we'll see...
Bonus tracks or unreleased tracks are not bad tracks per se, just because they are not in the record. Usually songs that are left out of a record and used, or not, as bonus tracks, are left out because in a way, the artist feel dont fit with the rest of selected songs, not because they are not good songs.
Remembrance Day was left out from KTGC, not because it was bad, but because it didn't fit with the general sound of that record, for example. Luckily it fit on GL, but if MK had decided it didn't fit either by whatever reason, it would had been left out too.
I remember a conversation with Chuck Ainlay long ago by mail, in which he told me that some great songs from MK are left out of records because of that, saved for maybe another record, but then it didn't fit with the next, and not to the next again, and as MK has many new songs, he forget about them.
