After listening to both discs from the Deluxe version, I have to say I'm really leaning towards Barbra and the quartet. The songs have a more intimate sound as if Barbra were performing these songs in a small jazz club. The arrangements and the voice are beautiful and pure in it's simplicity. One of my new all-time favorite Streisand songs is Where Do You Start? It is in a word sublime. I can't stop listening to it. Brava, Barbra
