The Lennon Sisters were a singing group consisting of four siblings:

• Dianne (born December 1, 1939)
• Peggy (born April 8, 1941)
• Kathy (born August 22, 1942)
• Janet (born June 15, 1946)

They were all born in Los Angeles, California.

These singers debuted on The Lawrence Welk Show in 1955. They were a mainstay on the show until they left to start a career of their own in 1968. The quartet was only three members from 1960 to 1964; oldest sister Dianne got married, left the group, and then rejoined them again.

In 1969, the sisters starred in their own variety show, Jimmy Durante Presents the Lennon Sisters Hour . Six weeks before the show premiered, the sisters were forced to deal with the shooting death of their father, by a deranged fan. The show lasted one season.

In the 1970s, the sisters performed regularly on The Andy Williams Show, and toured with Williams across the country.
