The Peanuts
were a Japanese vocal group consisting of twin sisters Emi (, ''Itō Emi'') and Yumi Itō (, ''Itō Yumi''). They were born in Nagoya, Japan on April, 1 1941. As
identical twins they had voices only slightly apart in timbre, which resulted in their singing together sounding like a solo artist utilizing double tracking or
reverb.
