I have this LP and it was also released in SQ
The SQ logo was on the cover
The Japanese LP with this 4 channel logo on them
are all RM that =QS
RM is a Japanese compromise so they did not
have to use Sansui QS logo
That makes sense, got some pretty rare Jap stuff from a guy who lived in Japan in the early 70's and has since moved here but this was the only Quad disc
