I'm listening to it just now, actually -- 'Wind and Rain' by Crooked Still (cannot seem to find lyrics online). It's one of those cheery ballads about a girl whose sister drowns her because she wants her man, and the drowned girl gets made into a musical instrument in the end, after floating along for some time. In this version, it's a fiddle, but Loreena McKennitt's 'The Bonny Swans' (http://www.songmeanings.net/lyric.php?lid=120724) is a variant of the same story, with a different refrain, and she ends up as a harp in that one. (Personally if I made instruments I would not make any bits of them out of finger-bones, but perhaps that's just me!)
