Here's the full version that Richard Dyer-Bennet used to sing, two verses of which I cited above many years ago:

An American variant as sung by Richard Dyer-Bennet,
with last verse composed by singer.

Frog Went a-Courting

Frog went a-courting, he did ride, mm-hmm,
Frog went a-courting, he did ride, mm-hmm,
Frog went a-courting, he did ride,
Sword and pistol by his side,
Mm-hmm, mm-hmm. mm-hmm.

He rode till he came to Miss Mouse's hall, mm-hmm,
He rode till he came to Miss Mouse's hall, mm-hmm,
He rode till he came to Miss Mouse's hall,
Where he most tenderly did call,
Mm-hmm, mm-hmm. mm-hmm.

Oh, Mistress Mouse, won't you come down, mm-hmm,
Oh, Mistress Mouse, won't you come down, mm-hmm,
"I dare not for my life come down,
'Cause Uncle Rat is away at town,
Mm-hmm, mm-hmm. mm-hmm.

But Uncle Rat he soon came home, mm-hmm,
Uncle Rat he soon came home, mm-hmm,
Uncle Rat he soon came home, mm-hmm,
Says, "Who's been here since I've been gone?"
Mm-hmm, mm-hmm. mm-hmm.

"Here's been a fine young gentleman," mm-hmm,
"Here's been a fine young gentleman," mm-hmm,
"Here's been a fine young gentleman,"
Who swears he'll marry me if he can,"
Mm-hmm, mm-hmm. mm-hmm.

Then Uncle Rat gave his consent, mm-hmm,
Then Uncle Rat gave his consent, mm-hmm,
Then Uncle Rat gave his consent,
And made a handsome settlement,
Mm-hmm, mm-hmm. mm-hmm.

Then Frog and Mouse lived happily, mm-hmm,
Then Frog and Mouse lived happily, mm-hmm,
Then Frog and Mouse lived happily,
And they were blessed with children three,
Mm-hmm, mm-hmm. mm-hmm.

And one did croak and two did squeak, mm-hmm,
And one did croak and two did squeak, mm-hmm,
One did croak and two did squeak,
And they had long tails and webbed feet,
Mm-hmm, mm-hmm. mm-hmm.
