I know this is an old post, but if you're interested I can tell you the name of the first piece.
It's a piano arrangement of the aria "Meine Lippen, Sie kuessen so heiss" by Franz Lehar, from his operetta, "Giuditta." It's often sung in English as "On my lips, every kiss is like wine"
The second piece sounds like it might be Lehar as well, but I can't identify it right off the bat.
Hope this helps!
