I’ve uploaded a contemporary ad for the LP which states that its release date would be January 22, 1969. The November 1968 date shown here now seems to be from a secondary source - be it Wikipedia, or the best guess of those managing Neil’s music streaming.
The release history of Neil Young is very convoluted and its best off heading to wiki to learn about Haeco CSG and such like...
Its a common misconception that all no name sleeves have the original mix while Neil Young sleeves have the remixed version. The Remix was issued on the 2 color label with the no name sleeve as well. Remix copies have RS6317A RE-1 in the wax on the A Side only.
An aural test to see if you have the remix is to listen to 'Here We Are In The Years' If it plays to the end with the clunking machine sound, its the Original Mix. If it fades out, its the Remix.
