I found another sound sample at Yahoo! Shopping and was able to transcribe a bit more:

...when in my heart I know you belong to someone else.
Oh, my darling, I just can't help myself. (I just can't help myself.)
(Why?) Why do I hurt inside?
(Why?) Why do you make me forget my pride?
(Why?) Why do I feel so blissful
(Why?) but so—ooh!—doggone pitiful?
