I'm the guy from the listening party in Madrid, as I told Capacity I only slept 3 hours ( 3 months baby) the night before the listening party and I was very tired.
I only heard one time each song, and Massive was the second one, I only remember that it was more raw, at the moment it seemed to me that were vocals of Mike and Chester but Derek opinion is more accurate for sure.
I heard the MT demos when there were released in each of the LPU but I havent listened again in a long time, and Its been like 15 years since i last saw the video of Wizard Song that is why I didnt recognised the Wizard Song beat with Mike.
BTH is the Mike demo, as I said many time that I did hear that versión.
And regarding Dont Stay as I Said in anonther chats I heard a song that had some of the beats but I think is contained in one of the other demos.
I tried to remember every detail to share with LP community but I'm getting old and my memory fails. Sorry for the misundertandings that my post produced
