Not to be confused with one of the sweaty ex-wrestlers that made up the British rock group the Dave Clark Five, Leonard Davidson was one of the early Ozark reedmen to become established in territorial bands in the Midwest. The first of which was Roland Bruce's Band, based out of Kansas City and happy to add Davidson to the roster circa 1918. Davidson was active playing around Nebraska, Oklahoma, and Texas over the next half of a decade, then shifted out to Hollywood in 1924. After a short period with a group led by the prickly Reb Spikes, the reedman then began some ten years of collaboration with the superb pianist and bandleader Sonny Clay.
Most of Davidson's appearances on recordings took place during this period in the context of bands such as Sonny Clay's Orchestra, Sonny Clay's Plantation Orchestra, the Dixie Serenaders, and the California Poppies, the latter two outfits also led by Clay. Such excellent sidemen as trumpeters Doc Hart and James "King" Porter were members of these groups. In 1933 and 1934 Davidson worked with drummer Alton Redd. Later jobs included several years in the mid-'30s with the Atwell Rose Band and a regular stint with Sammy Franklin's Orchestra. He retired from music in the mid-'50s and is presumed to be dead.
