Yoo, have I missed something?
I remember And One only getting drums recorded at NRG and never appearing again. That's at least what's in the book, and Jeff did write debatable stuff in his QnA.
Also wasn't the High Voltage remix made after the HT album sessions? Didn't Mike already confirm this year's ago?
The only song that I remember we don't 100% know what happened to, is Harmonic Song, which could refer to Crawling or PMA but also as well to another song, cause the title is super generic.
Maybe I misremember stuff, please enlighten me!
