As well as Astronomie Domine Pink Floyd also did Interstellar Overdrive.

Then there's Queen's "39":

In the year of '39 assembled here the Volunteers
In the days when lands were few
The ship sailed out into the blue and sunny morn
The sweetest sight ever seen

And as night followed day
So the storytellers day
That the score brave souls inside
For many a lonely day sailed across the milky seas
Ne'er looked back, never feared, never cried

Don't you hear my call though you're many years away?
Don't you hear me calling you?
Write your letters in the sand
For the day I take your hand
In the land that our grandchildren knew

In the year of '39 came a ship in from the blue
The Volunteers came home that day
And they bring good news of a world so newly born
Though their hearts so heavily weigh

For the earth is old and grey, little darling we'll away
But my love this cannot be
For so many years have gone, though I'm older but a year
Your mother's eyes, from your eyes cry to me

Don't you hear my call though you're many years away?
Don't you hear me calling you?
Write your letters in the sand
For the day I take your hand
In the land that our grandchildren knew

Don't you hear my call though you're many years away?
Don't you hear me calling you?
All your letters in the sand cannot heal me like your hand
For my life still ahead, pity me
