I really like the version by Robin Williamson on his Songs for Children of All Ages album.

FROGGY WOULD A-WOOING GO

Froggy would a wooing go
(cuddy alane. cuddy alane)
Froggy would a wooing go
   (cuddy alane and a')
Froggy would a wooing go
Whether his mummy would let him or no
   (keek maleerie, cowden down
   (cuddy alane and a')

He went to Mistress Mousie's door...
Where often he had been before...

He took Miss Mousie on his knee...
"Mousie will you marry me?"...

"Sir, I could not answer that...
Until I ask my Uncle Rat"...

Uncle Rat he laughed and cried ...
"This very night youll be a bride"...

Then they all sat down to dine..
Partaking of some sherry wine..

The piper was a bumble bee...
The drummer was a dark-eyed flea...

The fiddler was an old tom CAT!      (full stop there)
