A hilarious barnyard tale that plucks favourite characters from nursery rhymes and stirs them all together in one silly song! Old MacDonald had a dog... didn't he? Shy Little Jack Horner steps out of the corner to sing for his friends - but Mary, Mary, Quite Contrary can't stop butting in to tell the real story! Helaine Becker's witty text and Mike Boldt's quirky, dynamic illustrations are a perfect match in this lively romp that turns classic nursery rhymes on their heads! Full of familiar characters like Humpty Dumpty, Little Bo Peep, the Three Little Pigs, and Goosey Loosey, kids won't be able to resist giggling (and singing) along as Jack tries to remember who exactly was on Old MacDonald's farm!
