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.
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.
