Yep, it has been a source of frustration for many hardcore fanz too this blatantly poor management of the catalogue for many years. To the point that it is now hard to make heads or tails out of what really was released when..
Trouble is that no band member (with the noted exception of Manny) really did ever take a proactive interest in how these things were managed, it was simply left into the greedy hands of record companies to do what they like, misinform or whatever.
The first CD pressings were really poor audio, and some were hurridly put together, for example the first edition of Snaz. It would be years until the Snaz album got a proper full scale CD release, but even then they did not run all tracks in the right running order or even with the same tracks as the original album. I think it was Castle / or Eagle who put out a limited Snaz album, and then used some tracks of the "surplus" Snaz material as bonus tracks on the Fool Circle album... which was just a simple ploy to get fanz to buy both versions! The Salvo guys did a decent job of releasing for the first time a good version of Snaz on CD, where at least we got to hear all the songs, including Big Boy and Let me be your leader. However, I still do not think they included the studio songs "Jucy Lucy" and the remake of Morning Dew, but I may be mistaken. And, obviously, Salvo could not either resist the temptation to change the artwork, or add "factual" information..
Today, the issue is compounded by years of neglect of the original masters. I got the opportunity to sit in with Tim Turan who is an excellent mastering engineer -one of the best in the biz- and he said that the problem with the Naz catalogue now is that many of the original master tapes have been stored in somebody's loft, and that they had "40 winters and 40 summers". He did explain that you would get better sound from some of the early CD pressings / but obviously, these were not that good either... so it is a hard job to get the sound right.
But getting the information right is another matter & should blatantly be easier to do. However, this has still not happened, even with Salvo. The problem is that whoever seems to be in charge would like chime in with their two pennies worth of additional "information" and their versions of "the facts", plus retrospective views from the band.
Instead, I think it would be better to get the CDs excactly as THE ORIGINAL ALBUM, without any extra "outtakes" or viewpoints by "experts", journalists etc. The albums with the artwork and original liner notes were the origianal statement from the band, and should be kept as they initially intended, without any alternate takes, without early fading or whatever is the "in" thing to do now. Basically, opinions are like a-holes / everybody got one, and thus record co's should learn to zip it and leave the art (music, info, artwork) up to the artist.
In my view, in lack of the alternative, the Salvo remasters are the best option for now.
