Well, I'm still trying to prove that my tape is real - it's not the case of belief, I KNOW that this is real, but of course I understand the guys who not believe in that.
Anyway it caused me to do some deeper research and get in touch with the people who were involved into organising the Polish leg of "World Slavery Tour". Here's few key points of this research. Enjoy!
Roman Rogowiecki after hearing the tape is 100% sure that this is real, also he confirmed that the first 2 shows in Warsaw and Lodz was kind of experimental and the band was trying with some songs and the order of the songs - he said that 2 songs were originally in the setlist and were dropped after 2nd gig in Lodz. Unfortunately he doesn't remember what was the 2nd song - the first one, as he stated after hearing the tape, was definitely "Back In The Village". Mr Rogowiecki said that the second one could be "Flash Of The Blade", but he wasn't sure, so maybe let's not follow this thread - treat is as an urban legend please
Rogowiecki was a translator during the tour, he was travelling with the band and was the closest one to the band from the Polish crew. He is now a famous music journalist in Poland working for radio and TV.
Andrzej Marzec, the boss of Pagart Agency who organised the Maiden gigs claims that the Polish gigs at first was considered as a warm-up shows and pretented to not be an offiicial part of the tour. Due to very huge demand, they decided to join it as an official tour shows. Anyway he told that the band done some experiments during the first shows and wanted to try some elements of the show before going further to Europe. Also he said that during the bus travels from one town to another, they'd listened recorded shows from previous nights in the bus, analyzed the show flow and then decided which songs works well and which one are designed to be dropped out from the setlist.
The guy who was the camera director in the Polish part of the tour, mr Pawel Karpinski, said that first nights in Poland were a little bit messy and some elements of the shows were experimental. Both shows were filmed for the video which was supposed to be released later by Polish TV, but it was never happened. They allow to film only 2 songs: Aces High and Run To The Hills, but the audio were recorded in full. Video materials probably gone (erased or deleted), but the audio tapes recordings are exists - probably (again) it's a soundboard recordings from Lodz which are closed by the key in some archives. Where? Research is on...
So as you see, 3 key people who were involved into this shows, claims that's my tape is real.
And now a short note about mentioned above mr. Pelpow.... I wanted to make a comparison between my r2r and his material - it's the easiest way to check the key parts of the shows to see which one is legit (Bruce's screams when he saying the city name etc.). I decided to get in touch with him, as he is the only one who claims that he have the Warsaw bootleg. Unfortunately, mr Pelpow run like chicken, blocked me on the messenge without any response and called me an idiot on his personal fb profile. Why? Did he afraid of something? I'm leaving it to you.
In the opposite, John Miles who has fu**ing 7k boots of Maiden, was kind enough to give it a listen. And he had no doubts about the genuine of this material.
Also thanks to Luisma for detailed chats about the tape and other happenings.
The history goes on... Cheers to all Maiden maniacs out here!
