"Yes, yes," said John Kander, to the dozen men on folding chairs who had just finished another run-through of the song called "Hey, Hey, Hey, Hey!," which opens The Scottsboro Boys, a musical about a true travesty of American justice, about racism and anti-Semitism, hatred and hypocrisy, told in the form of a minstrel show put on by blacks with a white "interlocutor," or onstage ringmaster. It did not sell well enough on Broadway last season to stay there, but received 12 Tony Award nominations after it closed.
