Pearl hasn't changed one bit, folks. She's still big-hearted gospel Mama, giving out with the sermonettes, telling us all--""America, we better live as sisters and brothers."" Yes, America, we have sinned. Pearl frequents the White House and has lately become part of the US delegation to the UN. And she doesn't think we care enough about the handicapped and the neglected kids who run wild in the streets, the poor Indians, or each other. She erupts into verse now and then too, verse that would make Rod McKuen blanch. Included in the book are dollops of love from her fans who think she's the greatest and a telegram from Gerald Ford calling her ""Our Dear Ambassador of Love."" Now, about that spit. Pearl says we must ""rechew our cud""--that's our history, brethren--and spit out the bad parts. That's not all a body might bring up.
