Pipe organ. I listen to it (organlive.com) and there's a pretty good and well maintained Casavant at my church, but I never kept up my keys training enough to have a serious go at it.

Fiddle and cello. I have a good fiddle that was my grandfather's, and I can play it a little but there's not enough time to do it justice.

Drums. I love to mess around on a friend's kit, and I have some hand drums I enjoy, though I really want a kit. I play guitar because my folks didn't want a drum kit in the house. "Too big, too loud, too expensive.", they said. Now there's not enough space for the instruments I do have, never mind a drum kit. Maybe when I retire.

Peace, Mooh.
