The Aardvark Song (His Worship and the Pig)http://www.hisworshipandthepig.org.uk/index.html

In fact Mr & Mrs Sooz (AKA Stitherum) do a very good job of this song from Gainsborough Folk Club.

I don't have the lyrics, but if you want to hear His Worship & The Pig do it live then come to Faldingworth Live
