Thanks to Chris and Mike for the advice. Aunty had a little "dabble" with keyboards a while back, but her first love is still organs. She's in her 70's now and while she is a good musician the complexities of modern instruments are proving difficult for her. The organfax site looks very interesting and there does appear to be an organ group in Northern Ireland so perhaps she can make a contact there. Thanks for the advice guys - much appreciated.
