One of the original Western swing bands, the Light Crust Doughboys once featured the combined talents of Western swing's two most renowned figures, Bob Wills and Milton Brown. That lineup was unfortunately short-lived, due in large part to issues with the group's overly controlling manager, W. Lee Pappy O'Daniel (who would later become governor of Texas). However, even after all three of those figures were gone, the Light Crust Doughboys soldiered on, becoming one of the most popular pre-war Western swing bands in Texas; versions of the group continued to perform, off and on, well into the 21st century. The group's golden era is well represented on the 2007 compilation The Light Crust Doughboys 1936-1941, while a latter-day version of the combo took a lively look at the Doughboys' history on the epic-scale album 90 Songs, 90 Years.

The group that became the Light Crust Doughboys was formed in 1929 as the Wills Fiddle Band, when Bob Wills joined up with guitarist Herman Arnspiger in Fort Worth, Texas. The duo began playing dances and radio shows, and hooked up with singer Milton Brown in 1930. Brown's brother Durwood soon joined the band as a second guitarist, and banjoist Clifford Sleepy Johnson arrived not long after. The group landed a regular radio gig in Fort Worth sponsored by the Aladdin Lamp Company, and accordingly changed their name to the Aladdin Laddies. That didn't last long, however; in 1931, the band landed their own morning show on a rival station, sponsored by Burrus Mill, the makers of Light Crust Flour. Pappy O'Daniel managed the company at the time, and he convinced them to adopt Light Crust Doughboys as their new name. Still, O'Daniel disliked the group's music, dismissing it as "hillbilly"; he attempted to cancel the show after just two weeks, but popular demand kept the group on the air (as well as a deal with O'Daniel whereby the band members agreed to work in the flour mill).

With their regular radio show and wide-ranging musical repertoire (country, blues, jazz, pop, gospel, and more), the Light Crust Doughboys became one of the most popular and widely exposed bands in Texas. Musicians like singer/yodeler Leon Huff, steel guitarist Leon McAuliffe, and banjoist Johnnie Lee Wills began playing with the group. Realizing he had a good thing on his hands, O'Daniel became the Doughboys' manager and sometimes-songwriter as well as the show's announcer; he first moved the Doughboys to a new station, and then landed their show on a syndicated radio network that spread their sound across the Southwest. But his refusal to allow the band to play gigs outside the radio show was frustrating to its members, who felt they weren't seeing enough money. Wills, Johnson, and the Brown brothers recorded a single for Victor in 1932 under the name the Fort Worth Doughboys, which was a precursor to Milton Brown leaving the group several months later. Wills replaced him with Tommy Duncan, but clashed frequently with O'Daniel and wound up leaving himself in the summer of 1933, taking Duncan with him. Undeterred, O'Daniel reorganized the Doughboys and brought them to Chicago later in the year for a recording session with Vocalion. However, his days with the band were numbered as well; disputes with the Burrus Mill Company led to his being fired in 1935. O'Daniel put together a new band called the Hillbilly Boys, and thanks to his radio exposure, he made a successful run for governor of Texas in 1938. Meanwhile, the Light Crust Doughboys' new lineup had solidified by 1937: fiddle players Kenneth Pitts and Clifford Gross (plus Cecil Brower on occasion), banjoist Marvin Smokey Montgomery (who would remain with the group right up to his death in 2001), lead guitarist Muryel Zeke Campbell, rhythm guitarist Dick Reinhart, pianist John Knocky Parker, and bassist Ramon DeArman. This lineup's recordings were among the biggest-selling in their hometown, and were quite popular across the region thanks in part to their continued radio exposure, which then reached over 170 stations.

Their success continued right up to World War II, at which point most of the members joined either the Army or the defense industry. The Doughboys' radio show was thus canceled in 1942; Burrus Mill attempted to mount a new version of the program in 1946, featuring Jack Perry as the leader of the band (a post Smokey Montgomery took over in 1948). But despite a series of new recordings for King, interest had dissipated, and the radio show was canceled for good in 1950. While Montgomery kept the band going in some form, off and on, during the remainder of his life, the first large-scale revival of the Light Crust Doughboys took place during the '60s, featuring Montgomery (now on guitar as well as banjo), guitarist Billy Hudson, fiddler Johnny Strawn, bassist Artie Glenn, and steel guitarist Paul Blount. In 1995, the Light Crust Doughboys were named official musical ambassadors for Texas. During the '90s, when the band began recording again, the lineup featured Montgomery, guitarist Jerry Elliott, bassist Art Greenhaw, fiddlers John Walden and Jim Baker, and pianist Bill Simmons. Montgomery passed away on June 6, 2001, after a bout with leukemia.

With the passage of Smokey Montgomery, Art Greenhaw became the leader of the Light Crust Doughboys, and the group began adding elements of gospel, jazz, rockabilly, and modern country to the mix as they released a steady stream of albums in the 2000s and 2010s (15 between 2000 and 2019). The Doughboys' 2003 release, We Called Him Mr. Gospel Music: The James Blackwood Tribute Album, won a Grammy award for Best Southern, Country or Bluegrass Gospel Album. In 2019, the latest edition of the Light Crust Doughboys celebrated the band's past, present, and future for 90 Songs, 90 Years, with the group recording fresh versions of songs throughout their long and eventful history. ~ Steve Huey, Rovi
