Twin singing duo The Peanuts made their debut in 1959, and to celebrate their upcoming 50th anniversary, a new album is being released on November 26. The CD will contain several previously unpublished songs that they had recorded with the late composer Hiroshi Miyagawa.

The Peanuts, made up of sisters Emi and Yumi Ito, were very successful in the '60s and '70s. Their early career was launched by a string of covers and renditions of Japanese folk songs, but under the guidance of Miyagawa, they began releasing original hits.

From 1961 to 1965, they were well known for a morning radio program on the Nippon Broadcasting System. The new album, called "Nippon Housou da yo: Peanuts!!," features only songs that they sang on the popular "Kongetsu no Uta" segment of that show. While 8 of the 18 songs on the album are tunes that are already famous, the rest are previously unpublished works, whose recordings were apparently discovered only recently.

King Records is reportedly planning at least one more release for The Peanuts' 50th anniversary.
