THE MARROW SONG (OH WHAT A BEAUTY)
As recorded by the Billy Cotton Orchestra

1. Down the road there lives a man I'd like you all to know.
He grew a great big marrow for the local flower show.
When the story got around they came from far and wide,
And when the people saw the marrow, ev'rybody cried:

CHORUS: Oh, what a beauty! I've never seen one as big as that before.
Oh, what a beauty! It must be two feet long, or even more.
It's such a lovely colour, and nice and round and fat,
I never thought a marrow could grow as big as that.
Oh, what a beauty! I've never seen one as big as that before.

Oh, oh, oh, oh, what a beauty! We've never seen one as big as that before.

2. He was leaning on the garden gate the other day
And beckoned to a lady who lives just across the way.
He took her down the garden path and showed it her with pride,
And when she saw the size of it, the little lady sighed:

CHORUS: Ooh, what a beauty! She'd never seen … [etc.]

3. Then the flower show was held and ev'rybody went
To see the great big marrow lying there inside the tent.
Soon the judges came along to give the prizes out.
They only took one look at it and then began to shout:

CHORUS: Oh, what a beauty! We've never seen … [etc.]
