Lester Alvin Burnett (March 18, 1911 – February 16, 1967), better known as Smiley Burnette, was an American country music performer and a comedic actor in Western films and on radio and TV, playing sidekick to Gene Autry, Roy Rogers, and other B-movie cowboys. He wrote more than 400 songs and played proficiently over 100 musical instruments, sometimes more than one simultaneously. His career, beginning in 1934, spanned four decades, including a regular role on CBS-TV's Petticoat Junction in the 1960s.
Lester A. Burnett (he added the final "e" later in life) was born in Summum, Illinois, and grew up in Ravenwood, Missouri. He began singing as a child and learned to play a wide variety of instruments by ear, yet never learned to read or write music. In his teens, he worked in vaudeville, and starting in 1929, at the state's first commercial radio station, WDZ-AM in Tuscola, Illinois.
Burnette came by his nickname while creating a character for a WDZ children's program. He was reading Mark Twain's "The Celebrated Jumping Frog of Calaveras County" at the time, which included a character named Jim Smiley. He named the radio character Mr. Smiley and soon adopted the moniker as his own, dropping the title.
His break came in December 1933, when he was hired by Gene Autry to play accordion on National Barn Dance on Chicago's WLS-AM, on which Autry was the major star. As sound films became popular, Hollywood sought musical talent for Western films; and in 1934, producer Nat Levine cast Autry and Burnette in their film debut (unbilled) as part of a bluegrass band in Mascot Pictures' In Old Santa Fe starring Ken Maynard. Burnette sang and played accordion, and the film included two of his compositions.
He had other small parts until a secondary, but more prominent role in the 1935 serial The Adventures of Rex and Rinty. That same year, Levine gave Autry his first starring role in the 12-part serial The Phantom Empire, with Burnette playing Oscar, a comic-relief role. Mascot was soon absorbed by Republic Pictures, and Republic enjoyed enormous success with its musical Western features starring Autry. In each of the films, Burnette played Autry's comic sidekick, Frog Millhouse, with his trademark floppy black hat and trick voice (imitating a deep, froglike croak). Their association produced 62 feature-length musical Westerns.
Smiley Burnette wrote over 400 songs and sang a significant number of them on screen. He also composed musical scores for such films as The Painted Stallion and Waterfront Lady. His songs were recorded by a wide range of singers, including Bing Crosby, Ferlin Husky, and Leon Russell. His performance of "Steamboat Bill" appeared on Billboard's country chart in 1939.
By 1940, Smiley Burnette ranked second only to Autry in a Box-office magazine popularity poll of Western stars, the lone sidekick among the top 10, and when Autry left for World War II service, Burnette provided a sidekick to Eddie Dew, Sunset Carson, and Bob Livingston and appeared in nine other films with Roy Rogers. Burnette's movie horse, white with a black-ringed left eye, also became famous, first as Black-eyed Nellie, then as Ring-eyed Nellie, and finally as just Ring Eye.
After leaving Republic in June 1944, he became the sidekick to Charles Starrett at Columbia Pictures in the new Durango Kid series. Starrett and Burnette were paired in 56 films, from 1945 to 1952. When Starrett retired, Burnette was still under contract, so Columbia teamed him with Jock Mahoney for a new series of Westerns. A pilot film with Mahoney and Burnette was completed, but never released; Columbia then reassigned Burnette to its Gene Autry series, reuniting Burnette with his former partner.
Gene Autry retired from motion pictures in 1953, and other cowboy stars had either left the movies or were winding down their screen careers. With the studios no longer interested in making B Westerns, Burnette turned to broadcasting and made guest appearances on many country music radio and TV shows, including Louisiana Hayride, the Grand Ole Opry, and Ranch Party.
As the 1960s began, Burnette continued to make personal appearances at drive-ins, fairs, hospitals, town squares, and rodeos. Among other venues, he once appeared with Dewey Brown and the Oklahoma Playboys at a Friday-night dance at Jump's Roller Rink in Fairfax, Oklahoma. In the mid 1960s, he portrayed railway engineer Charley Pratt on the CBS-TV programs Petticoat Junction (106 episodes) and Green Acres (seven episodes).
Just after filming wrapped for the fourth season of Petticoat Junction, Burnette became ill. On February 16, 1967, a month before his 56th birthday, he died in Encino, California, from leukemia and was interred in Forest Lawn Memorial Park in Hollywood Hills, California. In 1971, four years after his death, Burnette was inducted into the Nashville Songwriters Hall of Fame.
