Folk & Traditional Song Lyrics www.traditionalmusic.co.uk The Cat 
The Cat 
All you that are married give ear to my song It is of frolic that lately was done By a young man and maid, if the truth I may tell The sport was so pretty it pleased me well 
By the light of a candle I happened to spy A pretty young couple together did lie Said Nelly to John if you'll pull up my smock You'll find a young hen full as good as your cock 
Then Johnny kissed her and pleased her awhile When he pulled up her smock it made him to smile Instead of a hen it appeared like a cat For there was her beard and her rough hairy back 
Then Nelly she opened her lily white thighs John played with the cat till the bristle did rise He stroked down the hair as black as a coal She catched his finger right snap in her hole 
Then Nelly she held him so fast in her arms While John was enjoying her beautiful charms He pushed in his dagger so stiff and so stout Saying I'll kill the cat and I'll knock her brains out 
A desperate battle between them was fought And John kept knocking poor pussy about The cat spit upon him and fought him so bo[l]d That pussy beat him right out of her hole 
The Nelly she held him so fast by the back While she wriggled her ass & cried push it in Jack He pushed in with courage so stout and so strong She smiled in his face crying well done John 
I burst in to laughter and spoiled the fun But Nelly kept crying push it in John Then John fell a laughing at Nell on her back And swore he'd no more be plagued with a cat. 
(anon, from a broadside in the Bodleian Ballad collection) 
Not tune specified, but various well known tunes would fit. E.g. Villikins, An alternative copy has [And she catched his pillock right slap in her hole] in
 verse 4. I didn't know of that meaning of pillock!
