NUBBIN. Old-Time, Breakdown. USA, Arkansas. C Major. Standard tuning (fiddle). AA'BB'. Source Jesse Wallace was unsure that "Nubbin" was the title of this 'raggy' tune, learned from Albert Lawrence (for which he also called it "Albert's Tune"). Drew Beisswenger (2008) notes that the second strain of "Nubbin" is similar to the second strain of Cyril Stinnett's "Padgett." Folklorist Vance Randolph included a tune called "Come Get Your Nubbin" in his 1954 list of Ozarks fiddle tunes printed in Midwest Folklore, Summer 1954, vol. IV: pp. 81-86), but it's relationship to Wallace's tune is unknown. Randolph noted  that the title was risqué: Nubbin referred to the penis in the first half of the 20th century in the region.
