The original was not a "Liberty" pressing, though they owned the company by the time it was issued. This was one of the transitional releases. The "originals" (mono and stereo) were still pressed in NJ by Plastilyte (sp).
Funny thing about "vinyl freaks" and "mastering freaks" is when lp was king, all the "audiophiles" had equalizers and created "road maps" for the best settings of favorite recordings. Now with cd domination, it seems to be "plug and play" and bitch.
