Thank you Bruce. Forgive my ignorance but what does the term 'maggot' refer too? I was posting this request on behalf of someone else and after searching the DT found Robin's Maggot and assumed it meant the insect!!! Have you an ABC for this tune ? I note from your site the refs : DMA11, CDM1 269,CDM5 67 but cannot find any files that relate. Many thaks again. Bev Lawton
