Back to Champagne Charlie for a moment...the chorus I've heard is soewhat longer and more complex than what's posted above. I rather expect the source for this version is a 1970s U.S. collection of British music hall songs (whose name and compiler I can't recall, sorry). I suspect this because where I learned it was at the Living History Centre's Dickens Christmas Fair, and that was the book (I happen to know, because I was staff librarian at the time) from which most of that group's music hall artistes got their material. Anyway, here's how it went:

For...
Champagne Charlie is my name,
Champagne drinking is my game,
Good for any game at night, my boys,
Good for any game at night, my boys,
All 'round town it is the same
By 'pop, pop, pop' I rose to fame.
Good for any game at night, my boys,
Who'll come and join me in a spree?
