The more things change, the more they stay the same, says folk singer Pete Seeger. Seeger, 72, was in Nashville for Thursday's opening of "Some Sweet Day," a musical drama about Arkansas sharecroppers who strike for better wages. "It's a subject that's completely timely even though the subject is 55 years old," said Seeger. "It's right up to date." Seeger gave moral support to fellow folk singer Si Kahn, whose songs provide the basis for "Some Sweet Day." Seeger, who recorded American folk, gospel union songs for posterity, said improved race relations are one hopeful sign he sees in modern times. "I just watched a group of about 20 black and white sub-teens walking through here, laughing and talking together, and it wasn't so long ago that you would have never seen that in Nashville," he said. "You've got to stay hopeful."
