Arriving UFO by Yes

Lyrics:
I could not take it oh so seriously really
When you called and said you'd seen a UFO
But then it dawned on me the message in writing
Spelt out a meeting never dreamed of before

I looked out, in the night
Strange and startling
Was the voice of time just saying
There's got to be a linking of everyone
Got to be a centre
It all comes flooding back

Arriving thru the eons of times immortal power of the future to behold
Vessels of a different impression, none that we could ever hope to have known

So look out, in the night
Once they arrive
Oh that perennial light

Impress a bolder Empire of Energy
In the ships we see
The coming of outer space

...

You say there's no reason to conjure
With the force as it has been known to be seen
You say I'm a fool a believer
Put your feet on the earth it is green

But look out, in the night
Wait for they arrive
To start such sciences anew
Here it is the coming of outer space
Such a pure delight
The coming of outer space
