TWO LITTLE SAUSAGES!
(Lyrics & Music by Lionel Monckton)
Sung by Gertie Millar and Edmund Payne

Once in a window of a ham and beef shop
Two little sausages sat!
One was a lady and the other was a gentleman
Sausages are like that!
He fell a victim to her simple charm,
And her form he would have embraced;
But a sausage you see never has any arms,
And the lady hasn't got any waist.

CHORUS

1. What a pair of happy little sausages!
Theirs was a very pleasant fate.
So they snuggled up together,
In the chilly weather,
Both on the same cold plate, well,
It wasn't such a very cold plate!

2. What a pair of silly little sausages!
Theirs was a very bitter pill,
For they quickly parted,
And it left her broken hearted,
While he joined a bad mixed grill, yes,
It really was a very mixed grill!

One sad day those sausages quarell'd,
Ended was all their joy.
The reason was that she said she caught him winking
At a saucy little saveloy.
'Pooh! My dear' said the gentleman sausage
'You may think I'm a flirt, well I am,
But I've seen you sitting on the same bit of parsley,
As that wicked old knuckle of ham.'

CHORUS (Same as before)

Long years after on a luncheon counter,
Those little sausages met.
She was engag'd to the wing of a chicken,
But he hadn't got off yet!
Soon they were reconciled, and then, of course,
She consented to name the day,
So the chambermaid dress'd her in a tissue paper frill
And the waiter gave her away.

LAST CHORUS
What a pair of jolly little sausages!
Nothing their happiness can dash.
And on any day you'll meet 'em,
For there's no one wants to eat 'em,
He calls her his own sweet mash,
So you see that they are sausage and mash!
So you see that they are sausage and mash!
