Don't know if Holloway sang it as a guest artist ... unlikely as those were the WWII Years.
No, Stanley Holloway recorded it, although I've never heard that version. Pater meus tells me that the version I cranked up so often was by John Charles Thomas.
And, as I remember it, one of the choruses went:
"Beware, take care, of the green-eyed Dragon with the fourteen tails,
He'll feed, with glee, on little boys, puppy dogs and big, fat snails.
So hurry up the stairs ..."
I think it was at the end of the first verse. The lyrics I posted have obviously been politically corrected. And since I haven't heard the song sung for probably 40 years, I consider this to be a considerable feat of memory.
