This 1967 recording, manufactured by the Japanese Decca branch and available in Japan only, is a true CD rarity. It comes in a slim CD package with the front cover very much in the Decca Grand Opera style (with the original LP cover photo of Suliotis), even though it does not formally belong to the Grand Opera line (mid-price). The modest booklet is entirely in Japanese, the track list in Japanese/Italian. As I am able to decipher, the Japanese text in the booklet consists of some very brief liner notes,

噂のナポリ版のライブ録音。リッカルドがテノールになっていたり、キーが異なる。あの有名なアリア“優しい声が私を・・・”もEs-durからC-durになっており全体が少しくすんだ感じがします。しかし一聴の価値はあるかなあ。
