Hi Baz thank's for looking. The sheet music is very elusive as is the midi. The only one thing I have found is a ended item on ebay for one used copy £20 I can find nowhere that it is offered as sheet music at all no music suppliers nothing. There are loads of mp3 and utube vids but no midi. First published in 1960 but long gone out of print probably because it is not the sort of thing someone would play. Also only the accompaniment is normally used because the actual duet content is more or less spoken.
