Checking at popsike it certainly looks like all mono promos has the unique mix - in most listings it's mentioned, but not all. So, I don't really know. One would think that this pressing woulda been withdrawn as soon as it was discovered. But then again, how many people do actually listen to whole promo LP's? Maybe it was never discovered... there can't be too many of it around though. But I'd take a shot at getting it from someone who doesn't know what he's selling. I did hehe - but I didn't know what I was buying either. I thought it was the regular LP, but mono, and almost fell over when that track hit me :)
Here's from a listing at popsike:
What makes this record unique is the alternate version of "Eagle Never Hunts The Fly" on side one. The label lists "Double Yellow Line" as the second song, but plays the alternate version of "Eagle". The song has added guitar effects in several places. Much more psychedelic sounding than the straight version that is also on the other side. I've heard other stock mono copies that played the regular songs, so I assume this was quickly corrected. I can only guess that just a handful of these exist, especially in this condition. I have never found any reference to this press in any of my Goldmine price guides. Comments or questions are welcome. The side one matrix numbers are 1732 A A1, and side two matrix numbers are 1732 B A1.
Maybe someone here got the facts on this pressing?
