This is fascinating stuff. I have too much time on my hands...
As Rob says, there are in fact differences between quite a few of the tracks on "Subterranean Omnidelic Exotour" and the later Edsel re-issue "The Omnidelic Exotour".
As has been previously noted, quitar-like 'stabs' and added synth lines are present on the latter, particularly on
The Quiet Men and
The Noise which has a noticeably longer intro.
Similarly on
Endlessly.
Exactly the opposite is true on
Through My Sleeping - the 'liquid' trickle at the beginning is missing on the Edsel version, which is shorter than the original.
There are also some subtle differences at the end of
This City on the first two releases. Like
Shifting City and
Burning Car it is the 'Subterranean' version that appears on the Edsel edition.
Thus, I think
four out of the five tracks on the Exotour 1997 EP are unique to that release, even if the differences are minor.
We have criticised the Edsel releases before in terms of their sound quality, and this is a good example.
Just For A Moment in particular suffers from too much loudness and loses some of the texture as a result.
