"Galaxy Song" is a Monty Python song that was written by Eric Idle who composed it with John Du Prez. The song first appeared in the 1983 film Monty Python's The Meaning of Life and was later released on the album Monty Python Sings. In 2014 the song featured in the live stage show Monty Python Live (Mostly).
The song originally appeared during the sketch "Live Organ Transplants". The surgeon (John Cleese), upon failing to persuade Mrs. Brown (Terry Jones) to donate her liver, opens the refrigerator doors to reveal a man wearing a pink morning dress (Idle) who accompanies her through outer space singing about the universe. This prompts Mrs. Brown to agree to the surgeon's proposal.
Just remember that you're standing on a planet that's evolving and revolving at 900 miles an hour, It's orbiting at 19 miles a second, so it's reckoned, the sun that is the source of all our power. The Sun and you and me, and all the stars that we can see, are moving at a million miles a day, In the outer spiral arm, at 40,000 miles an hour, of the Galaxy we call the Milky Way.
Our Galaxy itself contains 100 billion stars, it's 100,000 light-years side-to-side, It bulges in the middle, 16 000 light-years thick, but out by us it's just 3 000 light-years wide. We're 30,000 light-years from galactic central point, we go round every 200 million years, And our galaxy is only one of millions of billions in this amazing and expanding universe.
The universe itself keeps on expanding and expanding, in all of the directions it can whizz, As fast as it can go, at the speed of light you know, twelve million miles a minute, and that's the fastest speed there is. So remember, when you're feeling very small and insecure, how amazingly unlikely is your birth, Pray that there's intelligent life somewhere up in space, because there's bugger all down here on Earth.
