Coney Island Washboard Roundelay
You could hear her on the boardwalk every day
Soap suds all around
Tiny bubbles on the ground.
Rub-a-dub-a-dub
In her little tub
On those tunes she found.

Little thimbles on her fingers made the noise.
She played "Charleston" on the laundry for the boys.
She could rag a tune
Right through the knees
of a brand new pair
of (Blue Denim jeans // Levi jeans // BVDs)*,
Oh Coney Island Washboard Roundelay!

* The Mills Brothers recorded at least three different versions that I know of. The one I'm most familiar with is the one where they say "Levi jeans".

The version recorded in 1979 (see http://www.youtube.com/watch?v=sr5Yt3AVHVg ) on the Fairy Tales album is the one where they use the lyric "Blue Denim jeans". It's also a more syncopated version in some of the later renditions.

Hope this helps.
