The Lennon Sisters are an American singing group that includes four out of the eleven Lennon children. Dianne, Peggy, Kathy and Janet made their debut on the "Welk Christmas Television Show" in 1955 at the respective ages of 16, 14, 12 and 9. They were known as "America's Sweethearts of Song." The group frequently appeared on the "Lawrence Welk Show" from 1955 to 1968. Younger sister Mimi replaced Peggy upon her retirement in 1999. Dianne has since retired as well.
The Lennon sisters have many notable achievements including being inducted into the Vocal Group Hall of Fame, singing for seven of the U.S. Presidents and earning their own star on the Hollywood Walk of Fame. The Lennon sisters penned a memoir entitled "Same Song, Separate Voices" in 1989. They appeared on a number of different variety shows including the "Ed Sullivan Show" and "The Mickey Mouse Club." At one point they even had their own television show called "Jimmy Durante presents the Lennon Sisters Hour."
Lennon Sister merchandise included paper dolls, TV trays and coloring books. Parents considered them to be wonderful role models for their young girls because they always maintained that family and faith in God were the most important elements of their lives.
Three of the Lennon Sisters, Kathy, Janet and Mimi, are still singing as of 2015. "Saturday Night Live" also did a skit that was a spoof on the sisters.
