Funny thing: although this isn't the same song at all, it's another example of the name "Betsy Brown" being used for a woman who costs a man a lot of money. Coincidence?

From the sheet music at the Archive of Popular American Music at UCLA:

(I have improved the punctuation and inserted line breaks to emphasize the rhyme.)


BASHFUL BETSY BROWN
Words by Ed. Gardenier. Music by Winthrop Wiley.

1. Once there was a village maiden, just arrived in town,
Oh, so shy!
Met a fly young city chappie, said he'd show her 'round,
Wise young guy!
First he took her to the theatre, then they went to dine,
Me, oh, my!
How his roll of long green vanished, when she ordered wine,
Extra dry!
She grew timid, blushing sweetly, cast her blue eyes down,
When he sighed, "I love you, bashful Betsy Brown."

CHORUS: Oh, bashful little Betsy, a coy young country maid,
With cheeks like apples rosy, her hair in one long braid—
To see her look of wonder, when taking in the town,
She'd do you good; she really would, shy, bashful Betsy Brown.

2. As they strolled along the av'nue, glitter caught her eye—
Diamond ring!
She said, "Sir, please let me wear it till we say goodbye."
Cute young thing!
"I just dote on French mixed candy," said this damsel shy.
"Shop's right near!
Get five pounds imported bonbons. You run in and buy.
I'll wait here."
Sweets cost chappie just five dollars, came back with a frown,
Gone was diamond, also bashful Betsy Brown. CHORUS.
