Out Muckadilla way, long ago, lived a drover named Joe and his clever dog, Sue. Sue could do wonderful tricks. She was the best and smartest dog in the world. She was also the happiest dog in the world. Until Joe decided to move to the city so Sue could perform, and then they'd become rich and famous. Sue and Joe did become very rich and very famous. So famous they went to London to perform for the Queen. But fame and fortune was not enough . . . and Sue was the saddest dog in the world.
