A current thread about Willie Songs reminded me of the Railroad Bill songs{though I only know them as rhymes since I've never heard them sung}.

Here's a link to a post that I wrote in this thread thread.cfm?threadid=21456#1385309 "Help: Railroad Bill". That post contains a Railroad Bill rhyme from Dorothy Scarborough's 1925 book On The Trial Of Negro Folk Songs

That rhyme includes this verse:

"Well, the policemen all dressed in blue,
Comin down sidewalk two by two,
Wus lookin' fer Railroad Bill".
-snip-

That same rhyme also includes this verse:

"Standin' on the corner, didn't mean no harm,
Policeman grab me the arm-
Wus lookin' fer Railroad Bill."
