As performed by Oscar Brand on Back-Room Ballads, CMS Records CMS-101 (1949), below is my transcription. Jon has already gone over the major differences above, but it never hurts to include the full lyrics.

THE THREE COACHMEN

Three jolly coachmen sat in an English tavern
Three jolly coachmen sat in an English tavern
And they decided that
And they decided that
And they decided that
They have another flagon

CHORUS
For tonight we'll merry merry be
For tonight we'll merry merry be
For tonight we'll merry merry be
Tomorrow we'll be sober

Here's to the man that drinks light ale and goes to be quite sober
Here's to the man that drinks light ale and goes to be quite sober
He falls the leaves do fall
He falls the leaves do fall
He falls the leaves do fall
So early in October

CHORUS

Here's to the man that drinks stout ale and goes to be quite mellow
Here's to the man that drinks stout ale and goes to be quite mellow
He lives as he ought to live
He lives as he ought to live
He lives as he ought to live
He'll be a jolly fellow

CHORUS

Now here's to the girl who steals a kiss and runs to tell her mother
Now here's to the girl who steals a kiss and runs to tell her mother
She does a very foolish thing
She does a very foolish thing
She does a very foolish thing
She'll never get another

CHORUS

Here's to the girl who steals a kiss and lingers for another
Here's to the girl who steals a kiss and lingers for another
She's a boon to all mankind
She's a boon to all mankind
She's a boon to all mankind
She'll be a jolly mother

CHORUS
