"Don't This Road Look Rough and Rocky" is Flatt & Scruggs' 1954 song (Click here for lyrics in the DT). According to notes to Flatt & Scruggs 1948-1959 (Bear Family BDC 15472), it is credited to Flatt & Scruggs, and is "an old song which the Blue Sky Boys had recorded in 1936 as Can't You Hear That Night Bird Singing." There were black gospel songs with "rough and rocky road" in their titles before World War II (for example, Heavenly Gospel Singers version recorded in 1936), but they don't seem to have been related.
