Only because the tag line wouldn't leave my head. It's been around for years, not of my doing, and a friend of mine, Paul Hudson, who plays melodeon once had some T shirts made with a suitable image. So I had to have a song to give an excuse for the chorus, and I was surprised to find I couldn't find one on the web, so I had to write this..

Willy and his Betsy went swimming abroad,
Where the ocean ran deep and green,
And the wild breakers roared,
They swam and they swam until
They were far out in the spray,

And the sharks they played melodeons,
at the bottom of the bay,
And etc....

Betsy she grew fearful, and did presently call,
Oh can't we go home my dear,
I don't like it here at all!
I hear a ghostly organist
From far far away.

And the sharks they played melodeons,
at the bottom of the bay,
And etc....

But Willy he said Betsy there is nothing to fear,
And the noises that you mention,
Must be water in your ear.
There's no organ or organist
In all this foaming spray,

 

Just at that moment, from far far beneath,
There appeared a Hohner Pokerwork,
And a huge set of teeth,
And Willy and his Betsy
Were consume/ed on that day

By a shark playing melodeon,
From the bottom of the bay.

And the sharks they played melodeons,
at the bottom of the bay,
and etc....
