Ten year-old black Thaddeus, who first won fame with his Song of the Empty Bottles (1968), is still composing songs and playing them on his guitar, but on a camping overnight in the mountains, where the stars are big and bright, he becomes concerned about the air pollution back in the city. Later Thaddeus and his friends make posters and conduct a door-to-door campaign to persuade their neighbors to recycle their newspapers, but no one heeds them until Mr. Andrews tapes the boys singing Thaddeus' new song and a popular disk jockey plays it, with overwhelming community response. Thaddeus is still a likeable kid and he'll have many rooters, but Molarsky isn't doing would be emulators any good with the simplistic solution and instant success proffered here.
