question, could it simply be that Portobello belle was spliced in from another show from the time you mention in your analysis, but that the rest of the show is correct?
i find it a bizarre choice of locations to use as a "fake"
going to listen to the show and to the audience chatter now. Luxemburg slang is VERY particular.
No, because I analyzed the entire show and only highlighted Portobello Belle and Tunnel Of Love, as they contain more relevant and substantial aspects. I could mention aspects and characteristics of other songs in the show, but that would be quite long and tiring for most people. So, I am particularly confident in my analysis, to substantiate it, I delved deep into the musical processes of how the band changed arrangements, additional nuances...
For now, I only know that the recording named Luxemburgo 83 is fake, I cannot confirm any show or date with precision, but I can identify the period, the dates above not yet cataloged as bootlegs. The same thing with the bootleg 1983.xx.xx - Once upon a time in 1983, through my analysis, I realized which period of the tour this recording belongs to.
Now, if you or anyone else can look at the two recordings and try to identify some more clues that help identify the origin of the recording, you are always welcome, my limitation is the language, but my specialty is the aspects that I mentioned in the posts.
