Each episode, Carrie and David show us how to put a song together - the words, the tune, the instruments - and perform it so we can all sing along.

Carrie and David Grant are ready, and the Popshop is open for business. Every day, a new customer arrives seeking a song - a song to make them happy, a celebration song, a song for a friend. Any kind of song you can think of! It's up to Carrie and David, and their faithful dog Riff, to create, play and perform a brand new song - with help from everyone at home, of course.
