Oh no! Billy, the faithful school bus, has broken down and he is auctioned off to the farmer as a hen house. But who is this coming out of retirement, freshly painted, as the children's reading bus? Billy, of course, so let's have a party! This musical entertainment for infants is an enjoyable mix of song, verse, narration and dance. Also featured are basic number, time, colour and mechanical themes as well as opportunities for the children to include their own lyrics.
