Sixty-eight years have passed since The Lennon Sisters’ dynamic voices were discovered worldwide.

The sisters are still alive, between the ages of 67 and 83, married, and remain closer than ever. and Two of them have grandchildren, and three still perform today, amazing fans with their well-preserved voices.

Here is a look inside their lives today.

The Lennon Sisters are most likely America’s longest-standing singing girl group that emerged in the 1950s. The insanely talented group of sisters come from a Catholic musical family of eleven children and have been singing since childhood.

The sisters are Californians, born in Venice. Though not all eleven siblings had an affinity for the show business industry, the quartet of older sisters—Dianne (DeeDee), Peggy, Kathy, and Janet Lennon—always enjoyed harmonizing and singing.

Lawrence Welk Jr., the son of American artist and host Lawrence Welk, discovered the quartet. The eldest Lennon sister, Dianne, had gone to school with Welk Jr., and the pair had started dating.

One day after school, Welk Jr. brought the sisters home to his dad to perform for him. Welk Sr. was impressed by their talent, leading him to invite them to appear on his show, “The Lawrence Welk Show.”

In 1955, the band appeared on the show’s Christmas Eve TV broadcast, captivating the audience with their acapella rendition of “He.” The quartet quickly gained popularity and recognition for their musical prowess.
