Carl Tyler "Doc" Sprague (May 10, 1896 – February 21, 1979)[1] was an American country musician.

[1] Sprague grew up on a farm near Houston, Texas and learned traditional cowboy songs as a child.

During his college years at Texas A&M, he played in a band and, later on, worked as an athletic trainer.

[2] His debut sides were "When the Work's All Done This Fall" and "Bad Companions"; the former would go on to sell over 900,000 copies.

In the 1930s he moved to Bryan, Texas and ceased recording, though he would return to play folk festivals during the genre's resurgence in the 1950s and 1960s.
