I'm trying to find the original instrumentations of these so that they can be tagged. Since this specific title isn't mentioned in Grove Music for either of these composers, I think the title "Concerto appropriate all'organo" means "Concerto appropriated for the organ", in other words, it isn't the original title.

Does anyone know what concertos these were originally taken from? They probably should be moved to the page for the original instrumentation, as they are arrangements.
