Here are the lyrics from Harry's Blues, which is often unavailable lately, as linked by J.P. above. Also, here's a TAB.
LOUIS COLLINS
by Mississippi John HurtMrs. Collins weeped, Mrs. Collins moaned,
To see her son Louis leavin' home
The angels laid him awayThe angels laid him away,
They laid him six feet under the clay
The angels laid him awayMrs. Collins weeped, Mrs. Collins moaned,
To see her son Louis leavin' home
The angels laid him awayOh, Bob shot once and Louis shot too,
Shot poor Collins, shot him through and through
The angels laid him awayOh, kind friends, oh, ain't it hard?,
To see poor Louis in a new graveyard
The angels laid him awayThe angels laid him away,
They laid him six feet under the clay
The angels laid him awayOh, when they heard that Louis was dead
All the people they dressed in red
The angels laid him awayThe angels laid him away,
They laid him six feet under the clay
The angels laid him awayMrs. Collins weeped, Mrs. Collins moaned,
To see her son Louis leavin' home
The angels laid him awayThe angels laid him away,
They laid him six feet under the clay
The angels laid him away__________
Note: according to Hurt this song, his own composition, was based on a true episode
