After the show was cancelled, they partnered with Andy Williams to create a successful Las Vegas residency, which lasted a decade.

They continue to tour around the country and, until recently, performed annually with their Christmas show at The Andy Williams Moon River Theatre in Branson, Missouri.

Their youngest sister, Mary Frances, died in 1954 when she was 16 months old after wandering into the street from the front lawn and being struck by a car.

Pablo's great-great-great-grandfather, Bernardo Salgado De Oliberos, was born in San Andrés, Spain.

The quartet was a trio from 1960 to 1964 after DeeDee married and left the group; she rejoined in 1964 (although making a small handful of appearances throughout her years not on the show).

Peggy also specialized in barbershop, or counter-harmony, singing, taught to her by her father (who performed during the Big Band Era in a quartet with his own three brothers).

The girls idolized Patti Page's multi-track vocal sound, feeling they achieved something close to her smooth blend in their Dot recording of "Stars Fell on Alabama".

Kathy was especially fond of Connie Francis, evident in her solo recording of "Malaguena", which showcased her impressive vocal range.

Their full-bodied, homestyle choral blend was perfect for such yuletide favorites as "Adeste Fideles", "Christmas Island", "Faith of Our Fathers", "The Star Carol", and "Home for the Holidays".

On August 12, 1969, their father, William Lennon, was shot and killed in the parking lot of the Venice Golf Course in Marina Del Rey, where he worked as a private instructor.

The sisters discovered an unopened letter containing a cut-out of their father, a picture of a gun pointed at his head, and the words "High Noon" (the time of the murder).

[9] The sisters were devastated by their father's death, and in the wake of the murder, their new show was impacted by this tragedy and lasted only one and a half seasons.

When Peggy retired from singing in 1999, younger sister Mimi took her place, and when Dianne left for a second time in 2001, the act was a trio again for the rest of its run in Branson.

[10] They continue to tour across the country and appear annually with their Christmas show at The Andy Williams Moon River Theatre, marking twenty consecutive years of performing in Branson.

While continuing to play tour dates, Kathy and Janet Lennon have branched out into the toy market in 2006, designing and selling a line of "Best Pals" dolls.

The four original Lennon Sisters wrote an autobiography titled Same Song, Separate Voices, first published in 1985, with a new edition in 1995.
