Intro
       
       D                D        A           G
In the year of our lord eighteen hundred and eleven
   Bm        A
On March the seventeenth day
D                 D             A          G
I will raise up a beer and I'll raise up a cheer
Bm  A             G           D 
For Saccharomyces cerevisiae
G                     D           A               G
Yes here's to brewers yeast, that humblest of all beasts
G                D            G          A
Producing carbon gas reducing acetaldehyde
G                         D               A         Bm  
But my friends that isn't all -- it makes ethyl alcohol
G                    D                  A              D
Yes that is what the yeast excretes and that's what we imbibe
Pre-Chorus
G         D
Anaerobic isolation
A         Bm
Alcoholic fermentation
G    D
NADH oxidation
A
Give me a beer
[CHORUS]
Chorus (Li-Diddly-I):
G D A Bm A
G D A D
Verse 1
D                  D       A    G
My intestinal wall absorbs that ethanol
Bm                                        A
And soon it passes through my blood-brain barrier
D                          D                 A          G     
There's a girl in the next seat who I didn't think that sweet
Bm              A                G     D
But after a few drinks I want to marry her
G                D              A           G
I guess it's not surprising, my dopamine is rising
Bm                                 A
And my glutamate receptors are all shot
G             D                 A     Bm      
I'd surely be bemoaning all the extra serotonin
G      D                           A             D
But my judgment is impaired and my confidence is not
Pre-Chorus
G          D
Allosteric modulation
D            Bm
No Long Term Potentiation
G          D
Hastens my inebriation
A
Give me a beer
[CHORUS]
Chorus (Li-Diddly-I):
G D A Bm A
G D A D
Verse 2
D                  D        A              G
When ethanol is in me, some shows up in my kidneys
Bm                          A
And inhibits vasopressin by degrees
D             D                  A        G
A decrease in aquaporins hinders water re-absorption
Bm              A        G       D
And pretty soon I really have to pee
G                       D          A        G
Well my liver breaks it down so my body can rebound
Bm                              A
By my store of glycogen is soon depleted
G                     D            A       Bm
And tomorrow when I'm sober I will also be hungover
G                      D             A                  D
Cause I flushed electrolytes that my nerves and muscles needed
Pre-Chorus
G        D
Diuretic activation
A         Bm
Urination urination
G         D
Urination dehydration
A
Give me a beer
[CHORUS]
