I noticed when I got my DCC gold CD of A Night At The Opera, the disc label erroneously listed track 5 as "'36" (it's supposed to read "'39"). Do all pressings have this typo, or was it ever corrected? S/Z
Mine's the same as well. Looks like you've discovered an easy means with which to identify the first run pressing if DCC ever re-releases it.
Another irregularity can be seen on the slipcase and back cover of the Deep Purple - Made In Japan DCC, where it says "all selections writen by Gillan, Glover, Lord and Paice". The booklet does give a credit to Ritchie Blackmore too.
