The music began as an academic exercise using the tricky phrase structure of "Putting on the Ritz". After several abortive attempts to write lyrics for it, I decided it was purely an instrumental piece. It made me think of steam trains when I listened to it so I asked my brother Alan if he could provide me with some photos of the Mid-Hants Railway (commonly known as the "Watercress Line") for the YOuTube video.
