Dawn Parade, from the original Disney cartoon.
KS1/2: Suggested in QCA Unit 9 as example of music that describes animals.
KS3 idea: Can be viewed as an example of the march genre, drawing attention to the verbal counting and regular pulse and typical 'oompah' bass line. Notice how the march tempo that suits elephants is slower than would suit humans (perhaps contrast it with a typical Sousa march).
