Yes, that's one of my favourites too Andy. My current top favourite (really needs an organ, but I'll table it anyway) is Bach's Toccata and Fugue in D minor.
Mine is Chopin's Fantaisie-Impromptu which my father used to play when we were all together in my grandmother's sitting room. He played it better than his brother who was a music teacher!!
a limited repertoire, I would say, ladybirder.... my mother was seriously into choral and, apparently, was trilling away today. I haven't been able to visit as I am down with a fourth dose of this flu-thing....
