In addition (maybe not so useful to you if all you do is songs) a G alto recorder lets you do a heck of a lot. You've got the whole range of Highland pipe tunes without overblowing and with added chromatics, and you're only a bit short of the first position range of the fiddle (the high B is sometimes doable). Those two factors make it a great match for Scottish music. I have several G recorders, more than I can currently use: PM me if you want to take one off my hands.
