I have just had a response from the website owner 'Llwetrah'. Here it is (copied and pasted)....

> I found your version of Matty Groves from your website >(The Last Lay of Matty Groves). Would you mind telling >me who wrote it, or where it came from?

I wrote it. You're welcome to use it - that's why I write the things! Any acknowledgement (if you do so) when it's performed should simply be to 'Llewtrah'. In the realms of bawdy verse I don't use my own name.

Thanks,
