Eric, the last verse goes
"fear not little darlin' of dying, if the world be sovereign and free
For we'll fight to the last.."

The Intergalactic laxative was taught to me in the 70's by a mate, and I never knew it was a Donovan song. Here goes:

I was impressed like everyone, when man began to fly
Out of earthly regions to planets in the sky
With total media coverage, we saw the heroes land
As ceremoniously they disturbed the cosmic sand

In awe and admiration we listened to the talk
Such pride felt they, such joy, to be upon the moon to walk
My romantic visions shattered when it was explained to me
Spacemen all wear diapers in which they shit and pee

CH Oh the intergalactic laxative will get you from here to there
Relieve you and believe me without a worry or care
If pooping is your problem when you're out there in the stars
The intergalactic laxative will get you from here to Mars

They don't partake like you and I of beefy burger mush
Their food is specially prepared to dissolve into slush
Absorbed by multi-fibres in their super diaper suit
Otherwise their slush might trickle down inside their boots

You may well ask now what becomes of liquid they consume
A pipe is led from penis head to a unit in the room
The water is re-circulated, filtered for re-use
In case of anti-gravity, pee gets on the loose

Whenever man has conquered, in his quest for frontiers new
I'm glad he's always had to do, the number One and Two
It makes it all so ordinary, just like you and me
To know the greatest heroes, they had to poop and pee

The intergalactic laxative will get you from here to there
For cosmic constipation, there's none that can compare
If pooping is your problem when you're out there in the stars
The intergalactic laxative will get you from here to Mars
