Here's a composite I made from the lyrics posted by Mrrzy and Bald Eagle, along with a bit here and there from Jerry Silverman's 62 Outrageous Songs. I'll send the tune to Mudcat MIDIs.

BEER, BEER, BEER (CHARLIE MOPPS)

A long time ago, way back in history,
When all they had to drink was nothing but cups of tea,
Along came a bloke by the name of Charlie Mopps,
And he invented a wonderful drink and he made it out of hops (hops hops hops hops, etc).

Chorus:
He ought to have been an Admiral, a Sultan or a King
And to his praises we shall always sing.
Look what he has done for us: he's filled us with good cheer.
God bless Charlie Mopps, the man who invented beer. (beer, beer, beer, diddley, beer, beer beer)

Here in Chesterfield [substitute your own locale] we drink beer a lot.
Down Whittington Moor [ditto] on a Saturday night, the pace gets rather hot.
We'll drink a half, or sometimes two, it's cool and fresh and clear:
God bless Charlie Mopps, the man who invented beer.
Chorus

The Admiral, the Connaught, the Hole in the Wall as well;
No matter what their name is, it's Charlie's beer they sell.
So come along, my lively lads, at eleven o'clock they stop:
For five short seconds, remember Charlie Mopps. (One... two... three, four, five)
Chorus

A bushel of hops, a barrel of malt, you stir it around with a stick
The sort of lubrication to make your engine tick
40 pints of wallop a day will keep away the quacks
It's only fourpence ha'penny a pint and a shilling and tuppence in tax
(Chorus)

Music-hall, I presume, though I've only ever heard it from the singing of the late, great Dick Rendall, one time Squire of Manchester Morris Men. And I don't even know its official title.
