"Chim-chiminey, Chim-chiminey, chim chim cheroo"….the sweet ‘soot-covered’ character played by Dick Van Dyke sings this tune while sweeping the chimneys and dancing in the streets. Loveable Bert from the classic family movie “Mary Poppins” (1964) is a jack of all trades, makes friends with penguins and generally makes all folk, including Mary Poppins, smile. Made famous by the Walt Disney movie, Bert makes an excellent Book Week character in his stripy jacket, hat and broomstick.
