the Kendall Sisters
Cleveland, late 1940s - early 1960s
The Kendall Sisters were older sister Pauline "Polly" Kendall and Dorothy "Dolly" Kendall. They were born in West Virginia and grew up in the Wickhaven, PA area. They came from a musical family of Slovenian ancestry and learned the polka sound of their heritage. They were already a polished act, having played PA to Chicago inlcuding radio shows, when they moved to Cleveland in 1945.
The women joined with Ernie Benedict and the Range Riders/Polkateers. Ernie and his band were typical of many Cleveland bands from the late 1940s to mid 1950s as they played sets of polkas and pop music, or in Ernie's case, country, switching band names, instruments, and members when needed. The Kendalls took on the same dual personality, already well versed in the Cleveland style polka sound. The sisters were credited as playing guitar and bass in their own act, according to a 1948 Billboard magazine story.
The sisters and Benedict's band had long lasting radio shows
on WGAR (starting in 1945) and were on Cleveland's WNBK (later KYW then WKYC)TV once a
week. They left Benedict and hooked up with Kenny Bass, another
multi-genre Cleveland band leader and group.

The sisters were singing on some of Benedict's recordings, polkas under the Polkateers moniker and country/pop as the Range Riders, all of which were released on RCA records (there were a couple Range Riders records on the Continental label, one of which credits the Kendalls). They were credited as 'vocal refrain' on the sides. Most of Ernie's records had a vocal side and an instrumental side. They also sang on a couple of Kenny Bass's sides, which were released on Coral.

They recorded their own records in 1957-8. Dolly Kendall married Hillman Baker aka J.C. Hill ,who got his wife and sister-in-law a recording deal with Chess/Checker/Argo records. They recorded at Audio Recording. Many of the songs were written by the sisters with help from Baker and other Audio Recording folks. The first 45 "I'm Available" was written by Dave Burgess and recorded by several artists around the same time, competing with each other to see who could get a hit. The sisters' record lost out to Margie Rayburn. The second 45 "Yea Yea" is a rock-n-roll sound that shows they were keeping up with the latest sounds, it supposedly made the Billboard charts, although we couldn't find it there. Some discographies lits a 4th 45 on Checker, with the titles "Make It Soon" and "Three Wishes". The sources for the titles were the Chess family discography book. The book is in error, as the songs were recorded by Bill Hall and the Sonnets, a group from Nashville. It's not clear if the record was ever released at the time.

The sisters continued to perform into the early 1960s, and then retired. While the rest of the world knows them for their Argo 45s, Cleveland remembers them more for their time with Ernie Benedict and Kenny Bass. They are included in Cleveland's Polka Hall of Fame.
Pauline passed away in 2005.
This story from 1956 mentions a Kendall Sisters recording that doesn't seem to exist. The late Mr. Ryan of Athena records was not above self promotion when given the chance.
