I was a Ranting Sleazo more years ago than I care to remember and the song you are talking about was by a woman writer from the North -East called Pat Garrat.(She wrote a song called Kick the Cat which was quite well known) The first line was "Aw Pet Hinny come an' sit down here" We are from Merseyside and can't do a Geordie accent so we changed the words (without permission) to "E are darlin' etc..."
"Look at the arse on that" was in our version and in the original, so its not all our fault. I hope this helps.
