From the Fiddler's Companion:

SHAVING A DEAD MAN. AKA and see "Protecting the Innocent," "Shaving a Dead Nigger." Old-Time, Breakdown. USA, West Virginia. The tune first received its alternate title only in the 1970's in an attempt to purge it of racism. Rounder 0010, "Fuzzy Mountain String Band" (learned from Oscar Wright). Rounder 0089, Oscar & Eugene Wright - "Old Time Fiddle and Guitar Music from West Virginia" (learned from Ambrose Dunigan).

Dwight Diller even abbreviates the title (to "S.A.D.") to avoid being offensive (the tab is HERE).
