The chorus of the "Lancashire Liar" above looks rather familiar. What is the tune for it? Here's an early version of a well known song with practically the same chorus.

The Ram of Darby

As I was going to Darby,
All on a Market Day,
I met the finest Ram Sir,
That e'er was fed on Hay.
Indeed Sir it's a truth Sir
I never was known to Lye,
And if you'll go to Darby Sir,
You may see it as well as I.

The Wool upon its' Back Sir,
Reach'd up unto the Sky,
The Birds they built their Nests there,
For I heard the Young Ones cry.
Indeed Sir it's a truth &c.

The space between the Horns Sir,
Was far as Man could reach,
And there they built a pulpit
But no one in it preach'd.
Indeed Sirs it's a truth &c.

It had a Tail as long Sir,
As six Yards and an Ell,
Of which they make a Rope Sir,
To toll the Market Bell.
Indeed Sir it's a truth &c.

The little Boys of Darby
They came to beg his Eyes,
To roll about the Streets Sir,
They being of Foot Balls size.
Indeed Sir it's a truth &c.

The Butcher that kill'd this Ram Sir,
Was drowned in the Blood,
And all the People of Darby,
Were carried away in the flood.
Indeed Sir it's a truth Sir,
For I was never taught to lye,
And if you go to Darby Sir,
You may eat a bit of the Pye.

The song above was printed as song #70 in 'British Melodies', n.d. (c1805-15), by The Polyhymnian Co. and sold by George Walker, 106 Great Portland Street, London, with the music below. (George Walker was the Polyhymnian Co.) The song was also given without music in 'Encyclopedia of Comic Songs', London, 1819.
