Written and first recorded by Jimmie Rodgers in 1930, this classic country song became a signature tune for Bill Monroe a decade later. It was Monroe's first recording as a solo artist apart from his group The Monroe Brothers. His energetic cry "Good Moooooorning, Captain!" opens the yodeling tune about a proud mule skinner trying to land a job. A mule skinner is another name for a mule driver, who leads one or more of the animals to deliver goods to customers. Backed by his Blue Grass Boys band, Monroe assures the boss he is adept at handling the stubborn beasts (in this case, "skinning" is slang for "outsmarting").
Monroe secured a regular spot in the Grand Ole Opry when he auditioned with this song. He also sang it during his Opry debut at Nashville's War Memorial Auditorium in 1939 to an astounding response that resulted in the first encore heard in the history of the broadcast. That performance is included on the 1994 compilation Music of Bill Monroe From 1936 - 1994.
Monroe, known as the Father of Bluegrass, claimed the uptempo tune set the timing for bluegrass music. Biographer Neil Rosenberg noted that "Monroe had found a way to fuse the popular hillbilly songs of the time with the older string band music."
Monroe re-recorded this in 1950 as "New Mule Skinner Blues," with updated lyrics by George Vaughn (aka Vaughn Horton), who is sometimes listed as co-author of the original. In Rodgers' song, the narrator is a one-woman man trying to earn money to keep his lady well-stocked in booze and hats, but Monroe's take casts him as a lothario juggling three women. In "New Mule Skinner Blues," he's back to one broad. He also addresses the boss as foreman instead of captain.
