A&E's "Nero Wolfe" version of "Bei Mir Bist du Shön?

[Naphtali]

I own the eight-disk collection of A&E's "Nero Wolfe series, starring Timothy Hutton and Maury Chaykin. In the first non-pilot episode, "The Door Bell Rang," when just delivered huge crates are being opened, the background music sounds to me like a jazz or swing instrumental-only version of the Andrews Sisters' song, Bei Mir Bist du Schön." I have searched the worldwide web and the entire Montana library system to find this version of the song. No luck.

Can anyone help me out? If I am incorrect in believing the song is "Bei Mir Bist du Schön," that kind've explains why I can't find it. And if it is not, identify it if you can so I'll search correctly.
