I don't post too much any more but this issue has been discussed and commented on before. Likely by me.
It was very common in the earlier days of LPs (read vinyl) for the tunes on the master recordings to be sped up or slowed down so as to be able to fit on a vinyl album. Nothing more,. nothing less. Dead Set, Reckoning and of course, Europe '72 were all produced on vinyl first and likely the master that the records (remember that term?) were cut from had all those speed adjustments. If you have played along with LPs a lot as I and I am sure a bunch of other older folks on this forum have done in the past, you would discover not only differences in the pitch of an album but actually differences in pitch for individual songs on a given album. Remember it was all to make the tunes fit on a vinyl disc without having to cut the grooves closer together which would make the audio reproduction result have considerably less fidelity. In some ways that technique is similar to the distorted, crammed and compressed stuff we listen to today via 16-bit, 44khz digitally recorded CDs or the even the much worse digitally processed MP3s at 128k compression ratios beyond the 16-bit, 44khz digital reproduction standard.
Anyway... so much for nostalgia. No wonder high end hi-fi is still produced on vinyl and is making a strong comeback with audiophiles.
Hope this all makes sense.
