I notice that this re-issue duplicates the error from the original issue (which I bought in 1980). The track "Medicine Man" doesn't run to 4:57. It's more like 3:57. I wonder how come they didn't notice that?
Assuming (1) that the catalogue numbers were released in sequence, and (2) that where given, the years stated in the label discography on this site are correct, we can pin this LP to late-1983 or early-1984.
Many of them could be pinned down to the year by virtue of the cat number sequence, apart from those which (like this one) fall between two releases either side of a new year. It's not exact, but a good workaround.
I've been trying to find a reliable discography or release schedule for the label with no luck so far. However, I haven't given up yet so let's see. The label began in 1982.
I have actually emailed Universal (who bought EMI) although I don't expect a reply, but worth a shot I suppose.
