Fred McDowell's "Levee Camp Blues," which he recalled he put together in 1920 (he was 13 in the 1920 census), is based on a work song where the Captain has a Waterbury that won't keep time, as in when the heck is the guy going to notice that we should be done for the day already. Fred's March and August 1969 recordings of "Levee Camp Blues" are both worth a listen because the August one happens to get closer to "Ain't No More Cane In The Brazos" with Shine worked 'til he went stone blind. Arvel Gray born 1906 also knew the Captain has a "Waterbury" stuff.
