Yeah, me too, 100% that TR from MFN is from Alchemy, definitely.
Btw love the snare drum mix on that one, though the bass drums are bad.
And the Portobello is also, as J-F says, from that Paris show. Listened to that bootleg hundreds of times and it (at least 95%) is the same. Again, the drums mix is great imho (all the drums) and the whole song sounds reaally good, imho sometimes even better than Alchemy 96 remaster.
I remember when I first heard the London 22nd and 23rd July 1983 bootlegs a couple of years ago - it was a surprise for me to learn that they (it was really Terry W.) messed up the end of Solid Rock. Especially when a few days before that I had watched an MK interview from around the time Alchemy came out, and MK was confirming there were no edits at all and it was a recording of an actual one night. Despite the Solid rock ending editing, I agree with him very much - because there really were no overdubs and that's what counts for me - it really was live - something that, as I see it, wasn't very common those days and not many bands managed to this.
