Glass Scenery - the music box

I'd appreciate it if someone could tell me the titles of these two compositions, those that bookend this episode. The first one I'm aware is a classical piece, one that seems to have been ever-present in my life, something I've always enjoyed...yet I've never learned the title. The second one on the other hand, I'm not sure I've ever heard before, but it's just as lovely. For all I know it could perhaps be the latter part of the same piece. Never heard the whole thing, but yeah, would really like to know.

P.S. Just curious, anyone else find this episode to be the most ludicrous and inane of all those preceding it?
