Grandma was the organist and music director at St. Joseph's Church in Olney, Illinois for... 30 years? 40? 50?--a very long time, in any event, before finally giving it up a few years ago--and was a stickler for precise performance. She insisted on playing the organ for one son's wedding and two grandchildren's weddings, for a great-grandchild's baptism, and for countless other weddings and funerals besides a million or so regular Sunday masses.
The choir sang at her funeral mass this past Monday, of course, but the current organist was out of town, leaving them without an accompanist. But--but!--back in 2004-2006, the current music director had spent many sessions making digital recordings of Grandma playing the choir's entire repertoire on an electronic clavinova in case they ever found themselves without a backup organist...And that's how Grandma managed to pull off the exceptionally rare trick of playing at her own funeral. WIN.
