Hawkwind
"You'd Better Believe It"

I wandered far in lands unknown
Until I came to my earthly home
Far away I found life's dream
Drifting on a silver beam

You'd better believe it
It's so easy to say

Travelling at twice the speed of light
Orion's stars are high tonight
The gentle madness has touched my hand
Now I'm just a cosmic man

You'd better believe it
It's so easy to say
