So I thought I needed a third instalment of Mary Poppins, you know, to round things out. I chose to arrange Supercalifragilisticexpialidocious into a piano duet because the other two songs were bit melancholy (being in minor keys and all). There is no doubt this is a happy song, and to bump it up a notch from the usual marching band style I added a boogie-woogie bass part!
