T.W.Hornby? Well, this frivolous pastiche was composed for a charity concert some years ago - in aid of a Bulgarian home for disabled children with which one of my choir members had a strong connection. We helped fund a wheelchair. TW stands for 'timewalk', and Hornby is my middle name - a family name not connected - coupled maybe? - [unfortunately] to the 00-guage railway. It sounded much better performed live, but as the concert was not recorded this electronic version is the only way to 'perform' the music.
