Here you go - just listened to it and as Edward Woodward has such fantastic diction I could hear every word and wrote them down for you

CHAMPAGNE CHARLIE
(recorded by Edward Woodward)

Some people go for funny drinks
and down them by the pail
like coffee cocoa tea and milk
and even Adam's ale
for my part they can keep the lot
I never would complain
I wouldn't touch the bloomin stuff
I only drink champagne

chorus
Champage Charlie is my name
Champagne drinkiing is my game
There'e no drink as good as fizz fizz fizz
I'll drink every drop there is is is
All round town it is the same
By pop pop pop I rose to fame
I'm the idol of the barmaids and
Champagne Charlie is my name

whoever drinks at my expense has no need to complain
for everyone I treat alike I make them drink champagne

chorus
