Mrs Brown's Magical Music Box

Mrs Brown has a wonderful box.
A wonderful, magical, music box.
What is inside? Nobody knows.
Come inside and take a peek.
You might even need to stop tapping your feet.
Learn about rhythm, and musical beats.
March to the rhythm, and swing with me.
Come in and join the journey,
And learn along the way,
With Molly and her friends,
Let's get on our way!
