SLOWING DOWN TO LETHARGY
(Toby Fagenson)

Now we love to sing of the open sea
As the sailors used to do.
But it seems each time that we sing these songs
They take longer to get through.
We have no place for for a lively pace
As we plough on ploddingly.
Let each note sustain
And from oomph refrain
As we head toward Lethargy.


(Chorus)
Slowing down to Lethargy, me boys,
Slowing down to Lethargy.
We'll nail it hard with a big retard,
Slowing down to Lethargy.


If you wish to rush or you need to push
Won't you please control the urge,
As we sing each line with the energy
Of the average funeral dirge.
Six hellish months have passed away
Or so it seems to be,
Since our shantyman this song began,
Slowing down to Lethargy.


He called this tune by the light of the moon;
Well hello, here comes the sun!
Our tempo crawls, each syllable stalls,
And we've barely just begun.
Our song still booms, we are carried away
By our voices' glorious sound.
The verse is winding down at last;
Thank God we're chorus bound!


It's been far from fast, but we're home at last,
Now we're heaving into port.
As we disembark, hear some fool remark
That that song seemed far too short!
But don't you fret, we've a lot more yet,
And a snail's pace keeps its power,
As our voices boom into 'Fathom the Bowl'
For at least another hour.
