Going Japanese

Just read this on a site and I'm looking into it. Very interesting:

Back in the 70's and early 80's when the quality of American and even English LP's suffered from limitations in the vinyl supply caused by problems in the oil market, the audiofile standard became the Japanese LP. These were pressed on a heavy super vinyl banned in many countries due to the high PCP content in the factories where they were made. These were packed in heavy cardboard sleeves, with inserts including the lyrics in both English (if it was an English language artist) and Japanese. This may have had something to do with Japanese law requiring Japanese lyrics to be reviewed by censors
