go to: http://www.deltablues.comand do a power search...set the CUR/OLD sw. to OLD
and search for: [ lyrics | barlow ]
you'll find a SLOGAN verse about the BARLOW KNIFE and several references to tunes that included a verse referring to BARLOW KNIFE..."COTTON MILL" that Les mentioned is one, Doc Watson's "SHADY GROVE" is another and one or two more.
and I saw another song SOMEWHERE about THE BARLOW KNIFE..but at the moment cannot recall where or if I saved it to DISK...I generally do!
