All these songs are great.

We should have a drinking song

I suggest the anthem to Theakston's Old Peculier Ale.
(I finally got the lyrics from Dick Swain who says he can't remember the author - anybody know this?)

Some men take cider in the spring to make the sap rise frisky,
And when the autumn mists arise, some drive them out with whiskey.
Some say that naught but English Ale in summer's heat'll cool you,
But I've one drink all seasons 'round -- a pint of Old Peculier.
A pint of Old, a pint of Old, a pint of Old Peculier.
But I've one drink all seasons 'round -- a pint of Old Peculier.

For ague, gout, some men take rum. For fever, some take brandy.
Some keep the Hollands standing near. Some keep the porter handy.
Forsake such physics all, I say; let no such doctors rule you.
The one true cure, the nostrum sure -- a pint of Old Peculier.
A pint of Old, a pint of Old, a pint of Old Peculier.
The one true cure, the nostrum sure -- a pint of Old Peculier.

My youthful days I spent with maids, tasting their delights, sir.
Though greatly I enjoyed the days, I much preferred the nights, sir.
I lost my heart to Kate and Jane, and sold my soul for Julia;
But now the ranting days are done, I'm left with Old Peculier.
I'm left with Old, I'm left with Old, I'm left with Old Peculier.
But now the ranting days are done, I'm left with Old Peculier.

If wife should scold or children nag or trusted friend betrayed you,
With the magic potion in your hand, such slights will not dismay you.
If peevish master with new whim or foolish ways should school you,
Just come and drown your sorrows with a pint of Old Peculier.
A pint of Old, a pint of Old, a pint of Old Peculier.
Just come and drown your sorrows with a pint of Old Peculier.

And when your days are drawing down, and time begins to slip, sir.
Forget the ones who said they might; recall the ones who did, sir.
Let foolish fact be lost in time. Let kinder memories rule you,
And take some consolation in a pint of Old Peculier.
A pint of Old, a pint of Old, a pint of Old Peculier.
And take some consolation in a pint of Old Peculier.
