Answer to Question 1

 A blues singer rarely composes' self-consciously. Instead, lines and stanzas seem to just come,' sometimes in a rush but more often one at a time and widely spaced. Songs that blues singers memorize usually stick to one idea or event. . . . Today, a few blues songs are improvised in performance, but most are memorized beforehand. . . . In short, most blues singers today think a blues song should have a fixed, not variable, text. (Worlds of Music p. 208).

Answer to Question 2

 The music stops (all the instruments drop out) and,
 Unaccompanied, Lucas sings the words please have mercy on poor boy (this is known as a vocal tacet).
 Instruments quickly re-enter and end on a held note.
