Baton Rouge bus boycott: Baton Rouge bus boycott was a historic boycott launched on June 19, 1953 by the African-American residents of Baton Rouge, Louisiana.  Prior to the boycott, black people were forced to sit in the back of the bus, even when the front of the bus was empty.  Blacks made up about 80% of the ridership in the early 1950s and laws on the books prohibited black citizens from owning their own buses.  Demands for black riders to ride in the front of the bus, but still refrain from sitting next to whites, was supported by the City Council initially, and led to the passing of Ordinance 222.  However, the all-white fleet of bus drivers refused to enforce the ordinance and it was later overturned after the drivers went on strike.  The bus drivers strike lasted four days.  The drivers returned to work after the ordinance was overturned and declared victory.

At Parry's request Avdo undertook to produce an epic of similar extent to the "Iliad" (15,690 lines), since Parry needed to investigate whether a poet in an oral tradition would be able to maintain a theme over such length.  Avdo dictated, over three days and many cups of coffee (which, in turn, required much urination), a version of the well-known theme "The Wedding of Meho Smailagić" that was 12,323 lines long.  On another occasion he sang over several days an epic of 13,331 lines.  He claimed to have several others of similar length in his repertoire.
