Vinyl pressing mistakes


Ever seen an LP with the the wrong label? I have an old LP that has a different artist/album side pressed on the b side. I listened to the a side of 'Blue Man' by Steve Khan.... flipped it over and Tim Wiesebeg/Dan Fogalberg (sp?)'Power of Gold' or some such nonsence starts playing... surprise! How common are these mistakes? Just curoius.

Albert: Are you joshin' me or is that "Stoned screw up" really worth that much cash ? Was this a known problem on that album ? If it is true, my Dad will fall over when i tell him : ) Sean

I just picked up a two-box UK pressing of Revolver that is stereo on side 1 and mono on side 2. The jacket and labels say stereo but the matrix numbers are YEX for the first side and XEX for the second. I had to check after wondering why there wasn't any weird panning on the first few songs. The stereo side sounds good but the mono is really dynamic.
Unfortunately, the only vinyl pressing mistakes in my collection involve recordings that never should have been pressed at all, like all those digitally recorded LP's from the 1980's.

Anybody think they're worth anything? ;)
I have a few in my collection. Most amusing, I have an Andrew Hill record on Blue Note, B1-92051. On the jacket the title of the album is "Eternal Spirit", but on both the side 1 and side 2 labels it says "Internal Spirit". The whole Blue Note thing went to hell when Capitol took over. Just listen to the tin can sound of the latest Jason Moran CD. My Dionne Warwick box set also comes to mind. One of the records has two side one label on it. These things come up from time to time.
