Rob,
No. I only have references to Water Cresses. The attribution to Clifton of 'The Watercress Girl' is a mystery to me and confusing. it certainly doesn't appear in my lists so is therefore not mentioned on the back of any of his sheet music I have, but that doesn't exclude from being his. Some of it was more obscure and the odd piece was published by other than Hopwood & Crew.

The H&C number for Water Cresses is 496 which would put it c1863.

Roy, whilst being a well-loved and prolific writer, has been known to get things wrong.

BTW what is the song sung by I think The Young Tradition 'Watercress-o'? The chorus goes 'Watercress-o, watercress-o, won't you buy a little bundle of watercress-o.'
