CONEY ISLAND WASHBOARD
Words by Ned Nestor & Claude Shugart; music by Hampton Durand & Jerry Adams. ©1926.

1. Down by the beach lived the sweetest little peach
And I must say she just had the cutest way
Playing a chord upon a washboard.
Folks would gather 'round from ev'rywhere in town just to hear her play.

CHORUS: On her Coney Island washboard she would play.
You could hear her on the boardwalk ev'ry day
Soapsuds all around, bubbles on the ground
Rub-a-dub-a-dub in her little tub
All her tunes she found
Thimbles on her fingers made the noise
She played "Charleston" with the laundry for the boys
She could rag a tune right through the knees of your brand-new B.V.D.'s
With her Coney Island washboard roundelay

2. You never heard sweeter notes from a song-bird
Can't get enough when this baby does her stuff
She croons along when she plays a song
She's more than wonderful and more than marvelous; she just can't go wrong.
