Comment by Madame Streggae:
My copy has a mono sticker covering up the stereo reference on the rear sleeve but is actually stereo on all tracks. There's no 'stereophonic' banner on the label as on the image below.
Mighty disappointed as I don't like stereo for things I'd forever heard in mono and the vocals sound all wrong. Not sure whether every supposedly mono copy is stereo but don't propose buying another one to find up, or whether it was the case that some copies had the non-stereophonic labels put on to stereo copies in error?
