The Kim Sisters  was a South Korean female trio who made their career in U.S. during 1950s and 60s. They were Sue (Sook-ja), Aija (Ai-ja) and their cousin Mia Kim.. Sue and Aija were two of seven children of Kim Hae-song, a classical music conductor, and Lee Nan-young, one of Korea’s most famous singers before the Korean War, perhaps best known for “the Tears of Mokpo.” Mia’s father was Lee Bong-ryong, a musician as well.
The sisters arrived in Las Vegas, Nevada in 1959 and first performed at the Thunderbird Hotel, where producer Tom Ball did a show with Asian artists. Their successful performances at the Thunderbird led them to the Stardust where Ed Sullivan saw the trio and invited the sisters to perform on his show. The sisters performed on the Ed Sullivan show more than 22 times.
