Cyril Tawney sang Truro Agricultural Show on his album A Mayflower Garland.
He gave as his source Dr. Dunstan’s Cornish Dialect and Folk Songs, too.

Cyril Tawney: Truro Agricultural Show

TRURO AGRICULTURAL SHOW

Ee-I-O and away we go
To Truro Agricultural Show.

Good people all who hear my voice,
You now have reason to rejoice;
For off to Truro you may go,
To see the Agricultural Show.

CHORUS (after each verse):
But/So/And don’t go kissing the girls you know
At Truro Agricultural Show.

A motley group you will see there,
Fat farmers and their wives so rare;
Their bouncing daughters neat and clean,
With a pork-pie hat and a crinoline.

From Newlyn East, St Columb, too,
There’s hump-backed Jim and carroty Joe;
And a special train upon the rail
To bring all the thieves from Bodmin Jail.

They’ve got a band from Plymouth down,
The best that ever was in the town;
All the gentry will be there:
It’s twice as pretty at Whitsun Fair.

There’s horses, ponies, cows and calves,
Truro don’t do things by halves.
Devon bulls, sheep, pigs and geese:
You can see it all for a shilling apiece.

There’s things up there that’ll make you laugh;
There’s a two-legged cow and a nine-legged calf,
A billy-goat that comes from Wales
With sixteen eyes and seventeen tails.

Now all around I hear them say,
“We’ll see this show this very day;
Off we go, all in a row,
To Truro Agricultural Show.”

I’m glad you’re come, I see you’re here;
There’s thousands come from everywhere:
Rich and poor and high and low,
At Truro Agricultural Show.

Roy Palmer has nearly the same verses in his book A Touch on the Times.
