The song originally comes from the American 1966 musical "The Apple Tree", Music: Jerry Bock, Lyrics: Sheldon Harnick, Book: Jerry Bock + Jerome Coopersmith + Sheldon Harnick.and is based around three short stories all centering upon the Eve and temptation theme.
The song Gorgeous is sung on the original cast recording by the wonderful voice of Barbara Harris, I don't know whether the ad agency rerecorded the song for the ad or used the original, but it sounds very like the original to me!
Full lyrics are
"Look at me! I am gorgeous!
I am absolutely gorgeous!
There's this avalanche of beauty in one woman and I'm it!
Look at the way all of the parts fit together!
Stunning!
See the way my nose stopped running!
I was positive this creature was there inside the old me
All bottled up, waiting to get free.
Now I see the real me!
Look at that! Look at this! Look at those!
Let me just feel me!
Beautiful, glamorous, radiant, ravishing!
Look at the hair! Look at the shape! Look everywhere!
I am such a divine me!
Every studio will sign me!
My cup runneth over!
Who ever saw such a complete wow?
Nobody will say no to me now!
No one Is as
Gorgeous
As I Am!
